3 INFORMATION ABOUT THIS PROXY STATEMENT Why you received this proxy statement. You are viewing or have received these proxy materials because the Company’s Board is soliciting your proxy to vote your shares at the Annual Meeting. This proxy statement includes information that we are required to provide to you under the rules of the Securities and Exchange Commission (the “SEC”) and that is designed to assist you in voting your shares. Notice of Internet Availability of Proxy Materials. As permitted by SEC rules, the Company is making this proxy statement and its 2023 Annual Report available to its stockholders electronically via the Internet. On or about April 22, 2024, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials (the “Internet Notice”) containing instructions on how to access this proxy statement and our 2023 Annual Report and vote online. If you received an Internet Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. The Internet Notice instructs you on how to access and review the important information contained in this proxy statement and 2023 Annual Report. The Internet Notice also instructs you on how you may submit your proxy over the Internet. If you received an Internet Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained in the Internet Notice. Printed Copies of Our Proxy Materials. If you received printed copies of our proxy materials, then instructions regarding how you can vote are contained on the proxy card included in the materials. Householding. The SEC’s rules permit us to deliver a single set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as “householding” and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate set of proxy materials, as requested, to any stockholder at the shared address to which a single set of those documents was delivered.

4 QUESTIONS AND ANSWERS ABOUT THE 2023 ANNUAL MEETING OF STOCKHOLDERS Who is entitled to vote at the Annual Meeting? The Record Date for the Annual Meeting is April 16, 2024. You are entitled to vote at the Annual Meeting only if you were a stockholder of record at the close of business on the Record Date, or if you hold a valid proxy for the Annual Meeting. You will need to obtain your own Internet access if you choose to attend the Annual Meeting and/or vote over the Internet. Each share of our Class A common stock and our Class B common stock entitles its holders to one vote per share on all matters presented to our stockholders generally, and each share of Class C common stock and Class D common stock entitles its holders to ten votes per share on all matters presented to our stockholders generally. Holders of our Common Stock will vote together as a single class on all matters presented at the Annual Meeting. At the close of business on the Record Date, there were 13,000,253 shares of Class A common stock, 35,756,276 shares of Class B common stock, and 49,119,976 shares of Class C common stock issued and outstanding and entitled to vote at the Annual Meeting, representing 2.4%, 6.6%, and 91.0% of the voting power of our Common Stock, respectively. As of the Record Date, there were no shares of Class D common stock issued and outstanding and entitled to vote at the Annual Meeting. What is the difference between being a "record holder" and holding shares in "street name"? A record holder holds shares in his or her name. Shares held in “street name” means shares that are held in the name of a bank or broker on a person’s behalf. Am I entitled to vote if my shares are held in "street name"? Yes. If your shares are held by a bank or a brokerage firm, you are considered the “beneficial owner” of those shares held in “street name.” If your shares are held in street name, our proxy materials are being provided to you by your bank or brokerage firm, along with a voting instruction card if you received printed copies of our proxy materials. As the beneficial owner, you have the right to direct your bank or brokerage firm how to vote your shares, and the bank or brokerage firm is required to vote your shares in accordance with your instructions. If you haven’t received a 16-digit control number, you should contact your bank or broker to obtain your control number or otherwise vote through the bank or broker. How many shares must be present to hold the Annual Meeting? A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting, electronically or by proxy, of the holders of a majority in voting power of Common Stock issued and outstanding and entitled to vote on the Record Date will constitute a quorum. Who can attend the Annual Meeting? You may attend the Annual Meeting only if you are a Brilliant Earth Group, Inc. stockholder who is entitled to vote at the Annual Meeting, or if you hold a valid proxy for the Annual Meeting. The Annual Meeting will be held entirely online to allow greater participation. You will be able to attend the Annual Meeting and submit your questions by visiting the following website: www.virtualshareholdermeeting.com/BRLT2024. You will also be able to vote your shares electronically at the Annual Meeting. To attend and participate in the Annual Meeting, you will need the 16-digit control number included in your Internet Notice, on your proxy card or on the instructions that accompanied your proxy materials.

Online check-in will begin at 8:45 a.m., Pacific Time, and you should allow ample time for check-in procedures. If you hold your shares in “street name”

5 through a bank or broker, instructions should also be provided on the voting instruction card provided by your bank or brokerage firm. If you lose your 16-digit control number, you may join the Annual Meeting as a “Guest,” but you will not be able to vote, ask questions, or access the list of stockholders as of the Record Date. Why hold a virtual meeting? We are excited to embrace the latest technology to provide expanded access, improved communication and cost savings for us and our stockholders. We believe the virtual meeting will enable increased stockholder attendance and participation because stockholders can participate from any location. What if during the check-in time or during the Annual Meeting I have technical difficulties or trouble accessing the virtual meeting? We will have technicians ready to assist you with any technical difficulties you may have while accessing the virtual meeting website. If you encounter any difficulties accessing the virtual meeting website during the check-in or meeting time, the information for assistance will be located at www.virtualshareholdermeeting.com/BRLT2024. What if a quorum is not present at the Annual Meeting? If a quorum is not present at the scheduled time of the Annual Meeting, the person presiding over the Annual Meeting may adjourn the Annual Meeting until a quorum is present or represented. What does it mean if I receive more than one internet notice or more than one set of proxy materials? It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Internet Notice or set of proxy materials, please submit your proxy by phone, via the Internet, or, if you received printed copies of the proxy materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope. How do I vote? We recommend that stockholders vote by proxy even if they plan to participate in the Annual Meeting and vote electronically during the meeting.

6 If your shares are held in street name through a bank or broker, you will receive instructions on how to vote from the bank or broker. You must follow their instructions for your shares to be voted. Internet and telephone voting also may be offered to stockholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you would like to vote your shares online at the Annual Meeting, you should contact your bank or broker to obtain your 16-digit control number or otherwise vote through the bank or broker. You may visit www.virtualshareholdermeeting.com/BRLT2024 and enter the 16-digit control number included in the voting instruction card provided to you by your bank or brokerage firm. Can I change my vote after I submit my proxy? Yes. If you are a registered stockholder, you may revoke your proxy and change your vote: • by submitting a duly executed proxy bearing a later date; • by granting a subsequent proxy through the Internet or telephone; • by giving written notice of revocation to the Secretary of Brilliant Earth Group, Inc. prior to the Annual Meeting; or • by voting electronically at the Annual Meeting. Your most recent proxy card or Internet or telephone proxy is the one that is counted. Your virtual attendance at the Annual Meeting by itself will not revoke your proxy unless you give written notice of revocation to the Secretary before your proxy is voted or you vote electronically during the Annual Meeting. If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote electronically during the Annual Meeting. Who will count the votes? A representative of Broadridge Financial Solutions, Inc., our inspector of election, will tabulate and certify the votes. What if I do not specify how my shares are to be voted? If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. The Board’s recommendations are indicated on page 2 of this proxy statement, as well as with the description of each proposal in this proxy statement. Will any other business be conducted at the Annual Meeting? We know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, however, the proxy holders named on the Company’s proxy card will vote your shares in accordance with their best judgment. How many votes are required for the approval of the proposals to be voted upon and how will abstentions and broker non-votes be treated?

7 Proposal Votes Required Effect of Votes Withheld/Abstentions and Broker Non-Votes Proposal 1: Election of Directors The plurality of the votes cast. This means that the two (2) nominees receiving the highest number of affirmative “FOR” votes will be elected as Class III Directors. Votes withheld and broker non-votes will have no effect. Proposal 2: Ratification of Appointment of Independent Registered Public Accounting Firm The affirmative vote of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes) on such matter. Abstentions will have no effect. We do not expect any broker non-votes on this proposal. What is a “vote withheld” and an “abstention” and how will votes withheld and abstentions be treated? A “vote withheld,” in the case of the proposal regarding the election of directors, or an “abstention,” in the case of the proposal regarding the ratification of the appointment of BDO USA, P.C. as our independent registered accounting firm, represents a stockholder’s affirmative choice to decline to vote on a proposal. Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum. Votes withheld have no effect on the election of directors and abstentions have no effect on the ratification of the appointment of BDO USA, P.C. What are broker non-votes and do they count for determining a quorum? Generally, broker non-votes occur when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a particular proposal because the broker (1) has not received voting instructions from the beneficial owner and (2) lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the ratification of the appointment of BDO USA, P.C. as our independent registered public accounting firm, without instructions from the beneficial owner of those shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters, such as the election of directors. Broker non- votes count for purposes of determining whether a quorum is present. Where will I be able to find the voting results of the Annual Meeting? We plan to announce preliminary voting results at the Annual Meeting and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC shortly after the Annual Meeting. Will there be a question and answer session during the Annual Meeting? As part of the Annual Meeting, we will hold a live Q&A session, during which we intend to answer appropriate questions submitted by stockholders during the meeting that are pertinent to the Company and the meeting matters, for up to 15 minutes after the completion of the Annual Meeting. Only stockholders that have accessed the Annual Meeting as a stockholder (rather than a “Guest”) by following the procedures outlined above in “Who can attend at the Annual Meeting?” will be permitted to submit questions during the Annual Meeting. Each stockholder is limited to no more than two questions. Questions should be succinct and only cover a single topic. We will not address questions that are, among other things: • irrelevant to the business of the Company or to the business of the Annual Meeting; • related to material non-public information of the Company, including the status or results of our business since our most recent Quarterly Report on Form 10-Q; • related to any pending, threatened or ongoing litigation; • related to personal grievances; • derogatory references to individuals or that are otherwise in bad taste;

8 • substantially repetitious of questions already made by another stockholder; • in excess of the two-question limit; • in furtherance of the stockholder’s personal or business interests; or • out of order or not otherwise suitable for the conduct of the Annual Meeting as determined by the Chair or Corporate Secretary in their reasonable judgment. Additional information regarding the Q&A session will be available in the “Rules of Conduct” available on the Annual Meeting webpage for stockholders that have accessed the Annual Meeting as a stockholder (rather than a “Guest”) by following the procedures outlined above in “Who can attend at the Annual Meeting?”

9 PROPOSAL 1: Election of Directors At the Annual Meeting, two (2) Class III Directors are to be elected to hold office until the Annual Meeting of Stockholders to be held in 2027 and until each such director’s respective successor is elected and qualified or until such director’s earlier death, resignation or removal. We currently have seven (7) directors on our Board. The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the two nominees receiving the highest number of affirmative “FOR” votes will be elected as Class III Directors. Votes withheld and broker non-votes will have no effect on the outcome of the vote on this proposal. Our Board is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successor to each director whose term then expires will be elected to serve from the time of election and qualification until the third annual meeting of stockholders following election or such director’s death, resignation or removal, whichever is earliest to occur. The current class structure is as follows: Class I, whose current term will expire at the 2025 Annual Meeting of Stockholders; Class II, whose current term will expire at the 2026 Annual Meeting; and Class III, whose current term expires at the Annual Meeting and, if elected at the Annual Meeting, whose subsequent term will expire at the 2027 Annual Meeting of Stockholders. The current Class I Directors are Ian M. Bickley and Beth Gerstein; the current Class II Directors are Eric Grossberg, Attica A. Jaques, and Gavin M. Turner; and the current Class III Directors are Jennifer N. Harris and Beth J. Kaplan. In connection with the initial public offering (“IPO”) of our Class A common stock in September 2021 we entered into a Stockholders Agreement (the “Stockholders Agreement”) by and among the Company, Just Rocks, Inc., a Delaware corporation (“Just Rocks’), an entity jointly owned and controlled by our co-founders Beth Gerstein and Eric Grossberg, and Mainsail (as defined below). Pursuant to the terms of the Stockholders Agreement, each of Mainsail and Just Rocks have been granted certain Board designation rights so long as each maintains a specified percentage of ownership of our outstanding Common Stock. Beth Gerstein and Eric Grossberg have been designated by Just Rocks as a Class I and a Class II director, respectively. Gavin M. Turner and Beth J. Kaplan have been designated by Mainsail as a Class II and a Class III director, respectively. In addition, pursuant to the terms of the Stockholders Agreement, each of Mainsail and Just Rocks have agreed to vote, or cause to vote, all of their outstanding shares of our Common Stock at any annual or special meeting of stockholders at which directors are elected and to take all necessary action to cause the election of the Mainsail designated directors and Just Rocks designated directors. As a result of the Stockholders Agreement and the aggregate voting power of the parties to the agreement, we expect that the parties to the agreement acting in conjunction will control the election of directors of the Company. For more information, see “Corporate Governance—Stockholders Agreement” and “—Controlled Company.” If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote the shares of Common Stock represented by the proxy for the election as Class III Directors the nominees whose names and biographies appear below. All of the nominees whose names and biographies appear below are currently serving as our directors. In the event any of the nominees should become unable to serve or for good cause will not serve as a director, it is intended that votes will be cast for a substitute nominee designated by the Board or the Board may elect to reduce its size. The Board has no reason to believe that the nominees named below will be unable to serve if elected. Each of the nominees has consented to being named in this proxy statement and to serve if elected.

10 VOTE REQUIRED The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the two nominees receiving the highest number of affirmative “FOR” votes will be elected as Class III Directors. Votes withheld and broker non-votes will have no effect on the outcome of the vote on this proposal. RECOMMENDATION OF THE BOARD OF DIRECTORS NOMINEES FOR CLASS III DIRECTORS (CURRENT TERMS TO EXPIRE AT THE 2024 ANNUAL MEETING) The current members of the Board who are also nominees for election to the Board as Class III Directors are as follows: Name Age Director Since Position with the Company Jennifer N.

14 PROPOSAL 2: Ratification of Appointment of Independent Registered Public Accounting Firm Our Audit Committee has appointed BDO USA, P.C. as our independent registered public accounting firm for the fiscal year ending December 31, 2024. Our Board has directed that this appointment be submitted to our stockholders for ratification at the Annual Meeting. Although ratification of our appointment of BDO USA, P.C. is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice. BDO USA, P.C. served as our independent registered public accounting firm for the fiscal year ended December 31, 2023. Neither BDO USA, P.C. nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services. A representative of BDO USA, P.C. is expected to attend the Annual Meeting, have an opportunity to make a statement if he or she desires to do so, and be available to respond to appropriate questions from stockholders. In the event that the appointment of BDO USA, P.C. is not ratified by the stockholders, the Audit Committee will consider this fact when it appoints the independent auditors for the fiscal year ending December 31, 2025. Even if the appointment of BDO USA, P.C. is ratified, the Audit Committee retains the discretion to appoint a different independent auditor at any time if it determines that such a change is in the interests of the Company. VOTE REQUIRED This proposal requires the affirmative vote of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes) on such matter. Abstentions will have no effect on the outcome of the proposal. Because brokers have discretionary authority to vote on the ratification of the appointment of BDO USA, P.C., we do not expect any broker non-votes in connection with this proposal. RECOMMENDATION OF THE BOARD OF DIRECTORS

15 REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS The Audit Committee has reviewed the Company’s audited financial statements for the fiscal year ended December 31, 2023 and has discussed these financial statements with management and the Company’s independent registered public accounting firm. The Audit Committee has also received from, and discussed with, the Company’s independent registered public accounting firm the matters that they are required to provide to the Audit Committee, including the matters required to be discussed by the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Company’s independent registered public accounting firm also provided the Audit Committee with a formal written statement required by the applicable requirements of the PCAOB describing all relationships between the independent registered public accounting firm and the Company, including the disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence from the Company. Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. Jennifer N. Harris (Chair) Ian M. Bickley Attica A. Jaques

16 INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FEES AND OTHER MATTERS Set forth below are the fees of BDO USA, P.C., our independent registered public accounting firm, billed to us for the fiscal years ended December 31, 2023 and 2022 for audit services and billed to us in each of the last two fiscal years for other services: Fee Category Year Ended December 31, 2023 Year Ended December 31, 2022 Audit Fees $833,398 $601,747 Audit-Related Fees $37,371 $30,000 Tax Fees __ __ All Other Fees __ __ Total Fees $870,769 $631,747 AUDIT FEES For the year ended December 31, 2023, audit fees consist of fees for the audit of our consolidated financial statements for the year ended December 31, 2023, the review of the unaudited interim financial statements included in our quarterly reports on Form 10-Q, and fees billed in connection with the filing of a registration statement on Form S-8. For the year ended December 31, 2022, audit fees consist of fees for the audit of our consolidated financial statements for the year ended December 31, 2022, the review of the unaudited interim financial statements included in our quarterly reports on Form 10-Q, and fees billed in connection with the filing of registration statements on Form S-8 and Form S-3. AUDIT-RELATED FEES For the years ended December 31, 2023 and December 31, 2022, audit-related fees consist of fees for assurance and related services that are reasonably related to the performance of the audit and the review of our financial statements and which are not reported under “Audit Fees.” TAX FEES Tax fees comprise fees for a variety of permissible professional services rendered by the principal accountant for tax compliance, tax advice, and tax planning. There were no tax fees billed for the years ended December 31, 2023 or December 31, 2022. ALL OTHER FEES There were no fees billed for “other services” for the years ended December 31, 2023 or December 31, 2022. AUDIT COMMITTEE PRE-APPROVAL POLICY AND PROCEDURES The Audit Committee adopted a policy (the “Pre-Approval Policy”) in connection with our IPO, which sets forth the procedures and conditions pursuant to which audit and non-audit services proposed to be performed by the independent auditor may be pre-approved. The Pre-Approval Policy generally provides that we will not engage an independent auditor to render any audit, audit-related, tax or permissible non-audit service unless the service is either (i) explicitly approved by the Audit Committee (“specific pre-approval”) or (ii) entered into pursuant to the pre- approval policies and procedures described in the Pre-Approval Policy (“general pre-approval”). Unless a type of service to be provided by the independent auditor has received general pre- approval by the Audit Committee, it requires specific pre-approval by the Audit Committee.

17 For both types of pre-approval, the Audit Committee considers whether such services are consistent with the SEC’s rules on auditor independence. The Audit Committee will also consider whether the independent auditor is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with the Company’s business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance the Company’s ability to manage or control risk or improve audit quality. All such factors will be considered as a whole, and no one factor should necessarily be determinative. In connection with the Pre-Approval Policy, the Audit Committee may periodically review and pre- approve any services (and related fee levels or budgeted amounts) that may be provided by the independent auditor without first obtaining specific preapproval from the Audit Committee or the Chair of the Audit Committee. The Audit Committee may revise the list of general pre-approved services from time to time, based on subsequent determinations. The above-described services to the Company provided by BDO USA, P.C. for the fiscal years ended December 31, 2023 and 2022 were approved in accordance with the Pre-Approval Policy.

CORPORATE GOVERNANCE GENERAL Our Board has adopted Corporate Governance Guidelines, a Code of Business Conduct and Ethics and charters for our Nominating and Corporate Governance Committee, Audit Committee, and Compensation Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of the Company. You can access our current committee charters, our Corporate Governance Guidelines and our Code of Business Conduct and Ethics in the “Governance” section of the “Investor Relations” page of our website located at www.brilliantearth.com, or by writing to our offices at 300 Grant Street, Third Floor, San Francisco, CA 94108.

18 BOARD COMPOSITION Our Board currently consists of seven (7) members: Ian M. Bickley, Beth Gerstein, Eric Grossberg, Jennifer N. Harris, Attica A. Jaques, Beth J. Kaplan, and Gavin M. Turner. Our Board is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successor to each director whose term then expires will be elected to serve from the time of election and qualification until the third annual meeting following election or such director’s death, resignation or removal, whichever is earliest to occur. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. The division of our Board into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control of the Company. STOCKHOLDERS AGREEMENT In connection with our IPO, we entered into a Stockholders Agreement with (i) Mainsail Partners III L.P., a Delaware limited partnership and the Mainsail Holdcos (as defined in the Stockholders Agreement) (collectively, “Mainsail”), and (ii) Just Rocks granting each of Mainsail and Just Rocks certain board designation rights so long as each maintains a specified percentage of ownership of our outstanding common stock. Pursuant to the terms of the Stockholders Agreement, Mainsail has the right to designate (i) two of our directors for as long as Mainsail directly or indirectly, beneficially owns, in the aggregate, 15% or more of our Class A common stock (assuming that all outstanding common units of Brilliant Earth, LLC ("LLC Interests") are redeemed for shares of our Class A common stock on a one-for- one basis) or (ii) one of our directors for as long as Mainsail directly or indirectly, beneficially owns, in the aggregate, 5% or more of our Class A common stock (assuming that all outstanding LLC Interests in Brilliant Earth, LLC are redeemed for shares of our Class A common stock on a one- for-one basis), and Just Rocks shall have the right to designate (i) two of our directors, for as long as Just Rocks directly or indirectly, beneficially owns, in the aggregate, 15% or more of our Class A common stock and Class D common stock, combined (assuming that all outstanding LLC Interests are redeemed for shares of our Class A common stock or Class D common stock, on a one-for-one basis) or (ii) one of our directors for as long as Just Rocks directly or indirectly, beneficially owns, in the aggregate, 5% or more of our Class A common stock and Class D common stock, combined (assuming that all outstanding LLC Interests are redeemed for shares of our class A common stock or Class D common stock, on a one-for-one basis). Each of Mainsail and Just Rocks have agreed to vote, or cause to vote, all of their outstanding shares of our Common Stock at any annual or special meeting of stockholders at which directors are elected and to take all necessary action to cause the election of the Mainsail designated directors and Just Rocks designated directors. Additionally, pursuant to the Stockholders Agreement, we agreed to take all commercially reasonable actions to, among other things, cause (1) the Board to be comprised of at least seven (7) directors, or such other number of Directors as the Board may determine in accordance with the terms of the Stockholders Agreement and the Company’s organizational documents, (2) the individuals designated in accordance with the terms of the Stockholders Agreement to be included in the slate of nominees to be directors are to be elected at each annual meeting of our stockholders at which a director’s term expires; (3) the individuals designated in accordance with the terms of the Stockholders Agreement to fill the applicable vacancies on the Board; and (4) a Just Rocks designated director to be the Chairperson of the Board. In addition, Mainsail has the right, but not the obligation, to designate one (1) director to our Compensation Committee for so long as the Mainsail has the ability to designate at least one (1) director to the Board. The Stockholders Agreement allows for the Board to reject the nomination, appointment or election of a particular director if such nomination, appointment or election would constitute a breach of the Board’s fiduciary duties to our stockholders or does not otherwise comply with any requirements of our Amended and Restated Certificate of Incorporation or our Amended and Restated Bylaws or the Securities Act of 1933, as amended (the “Securities Act”) and Exchange Act of 1934, as amended (the “Exchange Act”).

19 The Stockholders Agreement will terminate upon the earliest to occur of (i) each of Mainsail or Just Rocks ceasing to own our Class A common stock, Class B common stock, Class C common stock or Class D common stock, (ii) each of Mainsail or Just Rocks ceasing to have any director designation rights, or (iii) as agreed unanimously in writing between us, Mainsail and Just Rocks. As a result of the Stockholders Agreement and the aggregate voting power of the parties thereto, we expect that the parties to the agreement acting in conjunction will control the election of the Company’s directors. Please see “—Controlled Company,” below. DIRECTOR INDEPENDENCE Our Board has affirmatively determined that each of Ian M. Bickley, Jennifer N. Harris, Attica A. Jaques, Beth J. Kaplan, and Gavin M. Turner qualifies as an “independent director,” as defined under the applicable Nasdaq Stock Market LLC rules (the “Nasdaq Rules”). The Nasdaq independence definition includes a series of objective tests, including that the director is not, and has not been for at least three years, one of our employees and that neither the director nor any of his family members has engaged in various types of business dealings with us. In addition, as required by the Nasdaq Rules, our Board has made a subjective determination as to each independent director that no relationships exist, which, in the opinion of our Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In evaluating and determining the independence of the directors, the Board considered that the Company may have certain relationships with its directors. Specifically, the Board considered that certain of our directors are affiliated with significant stockholders of the Company. There are no family relationships among any of our executive officers and directors. CONTROLLED COMPANY Mainsail and Just Rocks, in the aggregate, hold more than 50% of the voting power for the election of directors, and, as a result, we are considered a “controlled company” for the purposes of the Nasdaq Rules. As such, we qualify for exemptions from certain corporate governance requirements, including that a majority of our Board consist of “independent directors,” as defined under the Nasdaq Rules. In addition, we are not required to have a nominating and corporate governance committee or compensation committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities or to conduct annual performance evaluations of the nominating and corporate governance and compensation committees. Accordingly, our stockholders may not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the Nasdaq Rules. While currently five of the seven directors on our Board are independent under the Nasdaq Rules, and our Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee has each adopted a formal written charter and each consists entirely of independent directors under the Nasdaq Rules, for so long as we remain a “controlled company,” we may avail ourselves of exemptions available to “controlled companies” in the future. If at any time we cease to be a “controlled company” under the Nasdaq Rules, our Board intends to take any action that may be necessary to comply with the Nasdaq Rules, subject to a permitted “phase-in” period. DIRECTOR CANDIDATES The Nominating and Corporate Governance Committee is responsible for identifying and reviewing the qualifications of potential director candidates and recommending to the Board those candidates to be nominated for election to the Board, subject to any obligations and procedures governing the nomination of directors to the Board that may be included in the Stockholders Agreement. The Nominating and Corporate Governance Committee, in recommending director candidates for election to the Board, and the Board, in nominating director candidates, will

20 consider candidates who have a high level of personal and professional integrity, strong ethics and values and the ability to make mature business judgments. The Board believes that the Board membership should reflect a diversity of experience, qualifications, skills, gender, race and age in order to ensure that the Board, as a whole, has the necessary tools to perform its oversight function effectively in light of the Company’s business and structure. The Nominating and Corporate Governance Committee may also consult with outside advisors or retain search firms to assist in the search for qualified candidates, or consider director candidates recommended by our stockholders. Once potential candidates are identified, the Nominating and Corporate Governance Committee reviews the backgrounds of those candidates, evaluates candidates’ independence from us and potential conflicts of interest, and determines if candidates meet the qualifications desired by the Nominating and Corporate Governance Committee of candidates for election as director. Ms. Harris, one of our Class III Director nominees, was initially identified by a third-party search firm. Ms. Kaplan, one of our Class III Director nominees, was designated as director on our Board by Mainsail pursuant to the Stockholders Agreement. In evaluating director candidates (both new candidates and current Board members), the Nominating and Corporate Governance Committee in recommending candidates for election, and the Board may also consider the following criteria as well as any other factor that they deem to be relevant such as experience in corporate management, such as serving as an officer or former officer of a publicly held company; experience as a board member of another publicly held company; professional and academic experience relevant to the Company’s industry, operations, and target markets; ability to exercise mature business judgment, including, but not limited to, the ability to make independent analytical inquiries; leadership skills; experience in finance and accounting and/or executive compensation practices; whether a candidate has the time required for preparation, participation and attendance at Board meetings and committee meetings, if applicable; and diversity of background and perspective, including, but not limited to, with respect to age, gender, race and geographic background as well as diversity of expertise and experience in substantive matters pertaining to the Company’s business relative to other board members. In addition, the Board will consider whether there are potential conflicts of interest with the candidate’s other personal and professional pursuits. In determining whether to recommend a director for re-election, the Nominating and Corporate Governance Committee may also consider the director’s past attendance at meetings and participation in and contributions to the activities of the Board. Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials, to the Nominating and Corporate Governance Committee, c/o General Counsel, Brilliant Earth Group, Inc., 300 Grant Avenue, Third Floor, San Francisco, CA 94108. In the event there is a vacancy, and assuming that appropriate biographical and background material has been provided on a timely basis, the Nominating and Corporate Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others. COMMUNICATIONS FROM STOCKHOLDERS Stockholders of the Company may communicate directly with the independent members of the Board or any Chair of a Board committee about corporate governance, corporate strategy, Board- related matters or other substantive matters that our General Counsel consider to be important for the director(s) to know, by addressing any communications to the intended recipient by name or position in care of: Brilliant Earth Group, Inc., Attn: General Counsel, 300 Grant Avenue, Third

21 Floor, San Francisco, CA 94108, subject to compliance with the requirements and parameters noted below. Such communications may be made confidentially or anonymously. All communications, including stockholder recommendations of director candidates, must be accompanied by the following regarding the person submitting the communication: a statement of the type and amount of the securities of the Company that the person holds, and the address, telephone number and e-mail address, if any, of the person. The following types of communications are considered inappropriate for delivery to directors: • Communications regarding individual grievances or other interests that are personal to the party submitting the communication; • Communications regarding ordinary business operations; and • Communications that contain offensive, obscene or abusive content. Communications deemed to comply with the above requirements and to be appropriate for delivery will be delivered to the applicable director(s) on a periodic basis, generally in advance of each regularly scheduled meeting of the Board. Concerns relating to accounting, internal accounting controls, auditing matters or questionable financial practices will be handled in accordance with the procedures established by the Audit Committee with respect to such matters. BOARD LEADERSHIP STRUCTURE AND ROLE IN RISK OVERSIGHT Our Amended and Restated Bylaws and Corporate Governance Guidelines provide our Board with flexibility to combine or separate the positions of Chair of the Board and Chief Executive Officer in accordance with its determination that utilizing one or the other structure would be in the best interests of our Company. Mr. Grossberg, one of our co-founders, has served as Executive Chair of our Board since our formation and previously served as our co-Chief Executive Officer until March 2021. Ms. Gerstein, our other co-founder, serves as our Chief Executive Officer. We believe that the current separation of the roles of Chair and Chief Executive Officer is appropriate given our Company’s strategic and operational priorities. This structure allows the Chief Executive Officer to focus on our business and operations, while continuing to leverage the Executive Chair’s experience, perspective and vision to focus on long-term growth and strategic initiatives. Our Corporate Governance Guidelines provide that, if the Chair of the Board is a member of management or does not otherwise qualify as independent, the independent directors may elect a lead director. We currently do not have a lead director. Although the Chair of our Board is not an independent director and currently we do not have a lead director, our Board believes that separation of the positions of Chair and Chief Executive Officer, combined with the independent leadership of each of our Board committees, reinforces the independence of the Board from management, creates an environment that encourages objective oversight of management’s performance and enhances the effectiveness of the Board as a whole. Our Board of Directors has concluded that our current leadership structure is appropriate at this time, and will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate and in the best interests of the Company and its stockholders. The Board is responsible for overseeing our risk management process. Our Board focuses on our general risk management policies and strategy, the most significant risks facing us, and overseeing the implementation of risk mitigation strategies by management. Our Board is responsible for regularly reviewing information regarding and risks related to our credit, liquidity, and operations.

22 Our Audit Committee is responsible for reviewing and discussing our policies with respect to risk assessment and management, including with respect to financial, cybersecurity, and other information technology risks. In addition, our Audit Committee oversees management’s implementation of our cybersecurity risk management program. The Audit Committee receives periodic reports from management on our cybersecurity risks and risk-mitigation efforts, and our management updates the Audit Committee, as necessary, regarding any significant cybersecurity incidents. Our Nominating and Corporate Governance Committee manages risks associated with the independence of our Board of Directors. Our Compensation Committee is responsible for overseeing the management of risks relating to the Company’s executive compensation plans and arrangements. While each of our Board committees is responsible for evaluating certain risks and overseeing the management of such risks, our entire Board is regularly kept informed of through committee reports and is also kept apprised of particular risk management matters in connection with its general oversight and approval of corporate matters and significant transactions. The Board does not believe that its role in the oversight of our risks affects the Board’s leadership structure. ANTI-HEDGING POLICY Our Board has adopted an Insider Trading Compliance Policy, which applies to our directors, officers and employees. The policy prohibits our directors, officers and employees and any entities they control from short sales, transactions in puts, calls, or other derivative securities involving the Company’s equity securities, on an exchange, on an over-the-counter market, or in any other organized market, hedging transactions involving the Company’s securities, such as prepaid variable forward contracts, equity swaps, collars and exchange funds, or other transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of the Company’s equity securities pledging Company securities as collateral for a loan, purchasing Company securities on margin (i.e., borrowing money to purchase the securities), or placing Company securities in a margin account. A copy of the policy is available on our website at www.brilliantearth.com in the “Governance” section of the “Investor Relations” page. Clawback Policy Our Board has adopted a Policy for Recovery of Erroneously Awarded Compensation (the "Clawback Policy"), in accordance with the Nasdaq listing standards and Exchange Act Rule 10D-1, which applies to our current and former executive officers. Under the Clawback Policy, we are required to recoup the amount of any erroneously awarded compensation (as defined in the Clawback Policy) on a pre-tax basis within a specified lookback period in the event of any Financial Restatement (as defined in the Clawback Policy), subject to limited impracticability exceptions. Administration of the Clawback Policy is overseen and administered by the Compensation Committee. CODE OF ETHICS We have adopted a Code of Business Conduct and Ethics that applies to all of our directors, officers and employees including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of the code is available on our website at www.brilliantearth.com in the “Governance” section of the “Investor Relations” page. We intend that any amendments to the code, or any waivers of its requirements, that are required to be disclosed by SEC or Nasdaq Rules will be disclosed on our website.

23 ATTENDANCE BY MEMBERS OF THE BOARD OF DIRECTORS AT MEETINGS There were five meetings of the Board during the fiscal year ended December 31, 2023. Each director attended at least 75% of the aggregate of (i) all meetings of the Board during the period in which he or she served as a director and (ii) all meetings of the committees on which the director served during the period in which he or she served as a director. Under our Corporate Governance Guidelines, which are available on our website at www.brilliantearth.com, a director is expected to spend the time and effort necessary to properly discharge his or her responsibilities. Accordingly, a director is expected to regularly prepare for and attend meetings of the Board and all committees on which the director sits (including separate meetings of the Independent Directors), with the understanding that, on occasion, a director may be unable to attend a meeting. A director who is unable to attend a meeting is expected to notify the Chief Executive Officer or the Chair of the appropriate committee in advance of such meeting. We do not maintain a formal policy regarding director attendance at the Annual Meeting; however, it is expected that, absent compelling circumstances, directors will attend.

See Note 10, Equity-Based Compensation, to the financial statements included our audited consolidated financial statements for the fiscal year ended December 31, 2023 included in our Annual Report on Form 10-K filed with the SEC on March 28, 2024. The amount reported in this column reflects the aggregate grant date fair value for the restricted stock unit awards as determined for financial accounting purposes and does not correspond to the actual economic value that may be received by Mr. Kuo from this award. 2$13,200 of the amount reported for each of the named executive officers constitutes matching contributions made by us under our 401(k) plan, and $18,912 of the amount reported for Mr. Kuo constitutes a gross-up payment that is intended to make Mr. Kuo whole for the increased tax burden associated with Mr. Kuo’s status as a member of Brilliant Earth, LLC. NARRATIVE TO SUMMARY COMPENSATION TABLE Base Salaries Our named executive officers receive an annual base salary to compensate them for services rendered to our company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. Each of Ms. Gerstein’s, Mr. Grossberg’s and Mr. Kuo’s annual base salary was set in connection with the commencement of her or his service to us and is adjusted periodically. For fiscal year 2023, Ms. Gerstein and Mr. Grossberg each had an annual base salary of $600,000, which remained unchanged from fiscal year 2022. In early fiscal year 2023, Mr. Kuo’s annual base salary was adjusted from $375,000 to $430,000. The Summary Compensation Table above shows the actual base salaries paid to each named executive officer in 2023. The Compensation Committee retains the discretion to adjust each named executive officer’s base salary from time to time. Annual Bonuses In early 2023, the Compensation Committee adopted a bonus plan for the year ended December 31, 2023 (the “2023 Bonus Plan”). The Compensation Committee established financial metrics to measure Company performance in connection with awards under the 2023 Bonus Plan. The Compensation Committee determined that payouts of bonuses under the 2023 Bonus Plan would also be subject to individual performance goals and the Company meeting certain ESG goals for 2023. Ms. Gerstein’s target bonus under the 2023 Bonus Plan was $200,000, and in February 2024, the Compensation Committee approve a payout to Ms. Gerstein of $136,700 under the 2023 Bonus Plan. Mr. Grossberg’s target bonus under the 2023 Bonus Plan was $150,000, and in February 2024, the Compensation Committee approve a payout to Mr. Grossberg of $102,500

29 under the 2023 Bonus Plan. Mr. Kuo’s target bonus under the 2023 Bonus Plan was $200,000, and in February 2024, the Compensation Committee approve a payout to Mr. Kuo of $150,300 under the 2023 Bonus Plan. The Compensation Committee adopted a similar bonus plan for 2024. The Compensation Committee also retains the discretion to award discretionary bonuses from time to time. EXECUTIVE COMPENSATION ARRANGEMENTS On May 10, 2023, the Company entered into an employment agreement which superseded any prior employment arrangement with each of Ms. Gerstein and Messrs. Grossberg and Kuo, to continue to serve as our Chief Executive Officer, Executive Chairman, and Chief Financial Officer, respectively. These employment agreements provide for at-will employment, an annual base salary, and eligibility to participate in the health and welfare benefit plans and programs maintained by the Company. Each employment agreement provides that each named executive officer remains a party to a previously executed proprietary information and inventions agreement with the Company (or its predecessor in interest, as applicable). Pursuant to Ms. Gerstein’s employment agreement, for the year ended December 31, 2023, in addition to her annual base salary of $600,000, she is eligible to earn an annual cash performance bonus targeted at a percentage of her base salary determined at the discretion of our Compensation Committee. The amount of the bonus payable in respect of the fiscal year ended December 31, 2023 was based on the attainment of Company financial performance metrics established and evaluated by the Board or the Compensation Committee. Pursuant to Mr. Grossberg’s employment agreement for the year ended December 31, 2023, in addition to his annual base salary of $600,000, he is eligible to earn an annual cash performance bonus targeted at a percentage of his base salary determined at the discretion of our Compensation Committee. The amount of the bonus payable in respect of the fiscal year ended December 31, 2023 was based on the attainment of Company financial performance metrics established and evaluated by the Board or the Compensation Committee. Pursuant to Mr. Kuo’s employment agreement, for the year ended December 31, 2023, in addition to his annual base salary of $430,000, Mr. Kuo was eligible to earn an annual cash performance bonus targeted at a percentage of his base salary determined at the discretion of our Compensation Committee. The amount of the bonus payable in respect of the fiscal year ended December 31, 2023 was based on the attainment of Company financial performance metrics and individual performance objectives established and evaluated by the Board or the Compensation Committee. Equity Compensation In March 2023, our Compensation Committee approved a grant of 205,223 restricted stock units relating to our Class A common stock to Mr. Kuo under the 2021 Plan. The restricted stock units vest as follows, subject to Mr. Kuo’s continued service with us through the applicable vesting date, as to 25% of the restricted stock units initially subject to the award on February 15, 2024, and as to 1/16th of the restricted stock units initially subject to the award on each quarterly anniversary thereafter until the award is fully vested. Other Elements of Compensation Retirement Plans We currently maintain a 401(k) retirement savings plan for our employees, including our named executive officers, who satisfy certain eligibility requirements. Our named executive officers are eligible to participate in the 401(k) plan on the same terms as other full-time employees. The

30 Internal Revenue Code allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. Currently, we make safe harbor matching contributions in the 401(k) plan up to a specified percentage of each NEO’s contributions, and these matching contributions are fully vested as of the date on which the contribution is made. We believe that providing a vehicle for tax-deferred retirement savings though our 401(k) plan, and making fully vested matching contributions, adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our NEOs, in accordance with our compensation policies. Each NEO received Company-paid matching contributions under the 401(k) plan in 2023. Health/Welfare Plans. All of our full-time employees, including our named executive officers, are eligible to participate in our health and welfare plans, including medical, dental and vision benefits; short-term and long- term disability insurance; and life insurance. No Tax Gross-Ups Other than as described below for Mr. Kuo, we have not made gross-up payments to cover our named executive officers’ personal income taxes that may pertain to any of the compensation paid or provided by our company. During fiscal year 2023, Mr. Kuo’s compensation and benefits were administered differently from employees of the Company because of his status as a member of Brilliant Earth, LLC. Specifically, as a result of being a member of Brilliant Earth, LLC, Mr. Kuo was required to pay self-employment taxes and we were not required to pay employer-funded employment taxes. As a result, we grossed Mr. Kuo up for the self-employment taxes he was required to pay as a result of being classified as a member. The intent of this payment was to return Mr. Kuo to the position he would have been in had he been classified as an employee of the Company.

Turner2 __ __ __ 2 As a partner in one of our principal investors, Mr. Turner does not receive any compensation for his service on our Board. Director Compensation Program In connection with our IPO, the Board adopted a nonemployee director compensation program (the “Director Compensation Program”), which became effective in connection with the completion of our IPO. Pursuant to the Director Compensation Program, our non-employee directors receive cash compensation as follows: • Each non-employee director receives an annual cash retainer in the amount of $50,000 per year. • The chairperson of the audit committee receives an additional annual cash retainer in the amount of $20,000 per year for such chairperson’s service on the audit committee. • The chairperson of the compensation committee receives an additional annual cash retainer in the amount of $14,000 per year for such chairperson’s service on the compensation committee.

34 • The chairperson of the nominating and corporate governance committee will receive an additional annual cash retainer in the amount of $8,000 per year for such chairperson’s service on the nominating and governance committee. Under the Director Compensation Program, non-employee directors may elect to receive restricted stock units in lieu of all or a portion of their annual retainers. In such case, the grant of restricted stock units, referred to as the Retainer RSU Grant, will be made automatically on the date of our annual stockholder’s meeting. The Retainer RSU Grant comprises the number of shares of our Class A common stock calculated by dividing (a) the amount of the annual retainer that is expected to be paid to such director from the grant date through the next annual stockholder’s meeting by (b) the average closing trading price of our common stock over the most recently completed month as of the grant date. Retainer RSU Grants vest on the earlier of the first anniversary of the date of grant or the date of the annual stockholder’s meeting immediately following the date of grant. In order to receive a Retainer RSU Grant, the electing non-employee director must make an election in the time and manner specified in accordance with the Director Compensation Program or will otherwise receive the retainer in cash. Generally, this requires that (i) non-employee directors who are initially elected to our board of directors make their election prior to the date such individual first begins service, (ii) for all other directors within 30 days of the date on which the Compensation Committee adopted the program, or (iii) for all other non- employee directors, annual elections must be made no later than December 31, or such earlier date determined by the Board or the Compensation Committee, in the year prior to the year of service for which the annual retainer relates. Under the Director Compensation Program, each non-employee director is, in addition to the annual retainers, eligible to receive initial and annual awards of Class A common stock restricted stock units. Specifically, each non-employee director who is initially appointed or elected to our board of directors after our IPO, will automatically be granted, on the date on which the director commences services, a number of restricted stock units calculated by dividing (a) $140,000 by (b) the average closing trading price of our Class A common stock over the most recent completed month as of the grant date, rounded down to the nearest whole restricted stock unit, referred to as the Initial Grant. Additionally, each non-employee director who continues to serve on our board of directors as of immediately following the date of each annual stockholder’s meeting, will be granted a number of restricted stock units calculated by dividing (a) $140,000 by (b) the average closing trading price of our Class A common stock over the most recent completed month as of the grant date, rounded down to the nearest whole restricted stock unit, automatically on the date of each annual stockholder’s meeting thereafter, referred to as the Annual Grant. The Initial Grant will vest on the first anniversary of the applicable date of grant, subject to continued service through the applicable vesting date. The Annual Grant will vest on the earlier of the first anniversary of the applicable date of grant or the date of our annual stockholder’s meeting immediately following the date of grant, subject to continued service through each applicable vesting date. In the event of a change in control, each Initial Grant and Annual Grant, along with any stock options or other equity-based awards held by any non-employee director, will vest and, to the extent applicable, become exercisable immediately prior to such change in control.

35 SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT The following table sets forth information with respect to the beneficial ownership of our outstanding Common Stock, as of April 16, 2024, by: • each person known by us to beneficially own more than 5% of our Common Stock; • each of our directors and director nominees; • each of our named executive officers; and • all of our executive officers and directors as a group. The number of shares beneficially owned by each stockholder as described in this proxy statement is determined under rules issued by the SEC. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power. Applicable percentage ownership is based on 13,000,253 shares of Class A common stock, 35,756,276 shares of Class B common stock, and 49,119,976 shares of Class C common stock outstanding as of April 16, 2024. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of Common Stock subject to options, or other rights held by such person that are currently vested or exercisable or will become vested or exercisable within 60 days of April 16, 2024, are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person. Each outstanding share of Class B common stock and Class C common stock is convertible at any time at the option of the holder into one share of Class A common stock. In addition, each share of Class B common stock and Class C common stock will convert automatically into one share of Class A common stock upon any transfer, whether or not for value, except for certain permitted transfers described in our Amended and Restated Certificate of Incorporation, including transfers to family members, trusts solely for the benefit of the stockholder or their family members, and partnerships, corporations, and other entities exclusively owned by the stockholder or their family members, as well as affiliates, subject to certain exceptions. Once converted or transferred and converted into Class A common stock, neither Class B common stock nor Class C common stock will be reissued. Each share of Class C common stock will also automatically convert into one share of Class B common stock upon the earlier of (1) the 10-year anniversary of our IPO and (2) the date on which the Just Rocks ceases to hold at least 8% of the aggregate number of shares of all classes of common stock then outstanding, assuming exchange of all LLC Interests. Once converted into Class B common stock, Class C common stock will not be reissued.

36 Unless otherwise indicated, the address of all listed stockholders is 300 Grant Avenue, Third Floor, San Francisco, CA 94108. Each of the stockholders listed has sole voting and investment power with respect to the shares beneficially owned by the stockholder unless noted otherwise, subject to community property laws where applicable.

The Continuing Equity Owners may, subject to certain exceptions, exercise such redemption right for as long as their LLC Interests remain outstanding. In this table, beneficial ownership of LLC Interests has been reflected as beneficial ownership of shares of our Class A common stock for which such LLC Interests may be exchanged. When an LLC Interest is exchanged by a Continuing Equity Holder, a corresponding share of Class B common stock or Class C common stock will be cancelled. (2) Represents the percentage of voting power of our Class A common stock, Class B common stock, and Class C common stock voting as a single class.

38 CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS POLICIES AND PROCEDURES FOR RELATED PERSON TRANSACTIONS Our Board has adopted a written Related Person Transaction Policy and Procedures, setting forth the policies and procedures for the review and approval or ratification of related person transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we (including any of our subsidiaries) are, were or will be a participant, where the amount involved exceeds $120,000 in any fiscal year and a related person has, had or will have a direct or indirect material interest. Under the policy, our finance team is responsible for implementing procedures to obtain information with respect to potential related person transactions, and then determining whether such transactions constitute related person transactions subject to the policy. The Company’s Chief Financial Officer then is required to present to the Audit Committee each proposed related person transaction. In reviewing and approving any such transactions, our Audit Committee is tasked to consider all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be obtained in an arm’s length transaction and the extent of the related person’s interest in the transaction and take into account the Company’s Code of Business Conduct and Ethics. If advance Audit Committee approval of a related person transaction is not feasible, then the transaction may be preliminarily entered into by management upon prior approval by the Chairperson of the Audit Committee, subject to ratification of the transaction by the Audit Committee at the Audit Committee’s next regularly scheduled meeting. Management is responsible for updating the Audit Committee as to any material changes to any approved or ratified related person transaction and for providing a status report at least annually of all current related person transactions at a regularly scheduled meeting of the Audit Committee. No director may participate in approval of a related person transaction for which he or she is a related person. Unless noted otherwise, all of the transactions, agreements or relationships described in this section occurred prior to the adoption of this policy. The following are certain transactions, arrangements and relationships with our directors, executive officers and stockholders owning 5% or more of our outstanding Class A common stock or our Class B common stock. We believe that the terms of such agreements are as favorable as those we could have obtained from parties not related to us. TRANSACTIONS RELATED TO DIRECTORS, EQUITY HOLDERS AND EXECUTIVE OFFICERS Tax Receivable Agreement In connection with our IPO, we entered into a tax receivable agreement (the “TRA") with Brilliant Earth, LLC and the members thereof (the “Continuing Equity Owners”) which refers to the holders of Brilliant Earth, LLC interests and holders of our Class B common stock and Class C common stock following our IPO and related transactions, and includes Just Rocks, Beth Gerstein, Eric Grossberg, Jeffrey Kuo and Mainsail. The TRA provides for the payment by Brilliant Earth Group, Inc. to the Continuing Equity Owners of 85% of the amount of tax benefits, if any, that Brilliant Earth Group, Inc. actually realizes (or in some circumstances is deemed to realize), as a result of (1) increases in Brilliant Earth Group, Inc.’s allocable share of the tax basis of Brilliant Earth, LLC’s assets resulting from (a) Brilliant Earth Group, Inc.’s purchase of LLC Interests directly from Brilliant Earth, LLC and from each Continuing Equity Owner, (b) any future redemptions or exchanges of LLC Interests for Class A common stock, Class D common stock, or cash, and (c) certain distributions (or deemed distributions) by Brilliant Earth, LLC; and (2) certain tax benefits arising from payments under the Tax Receivable Agreement.

39 Registration Rights Agreement We entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with Holders (as defined below) in connection with our IPO. The Registration Rights Agreement provides the Holders with certain “demand” registration rights whereby, at any time after 180 days following our IPO and the expiration of any related lock-up period, a Holder can require us to register under the Securities Act the offer and sale of shares of Class A common stock issuable to them, at our election (determined solely by our independent directors (within the meaning of the Nasdaq Rules) who are disinterested), upon redemption or exchange of their LLC Interests. The Registration Rights Agreement will also provide for customary “piggyback” registration rights for all parties to the agreement. “Holders” refers collectively to holders of LLC Interests and our Class B common stock and Class C common stock immediately following consummation of our IPO and the transactions contemplated thereby, including our co-founders, Ms. Gerstein and Mr. Grossberg, Just Rocks, Inc. and Mainsail, who, following the consummation of the IPO, may exchange at each of their respective options, in whole or in part from time to time, their LLC Interests (along with an equal number of shares of Class B common stock or Class C common stock (and such shares shall be immediately cancelled)), as applicable, for, at our election (determined solely by our independent directors (within the meaning of the Nasdaq Rules) who are disinterested), cash or newly-issued shares of our Class A common stock or Class D common stock, as applicable. Stockholders Agreement In connection with our IPO, we entered into the Stockholders Agreement. The terms of the Stockholders Agreement regarding director designation rights and voting for the election of directors are described above in the “Corporate Governance” section under the header “Stockholders Agreement.” Indemnification Agreements We have entered into indemnification agreements with each of our directors and executive officers.
