Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Brilliant Earth Group, Inc. was formed as a Delaware corporation on June 2, 2021 for the purpose of facilitating an initial public offering ("IPO") and executing other related organizational transactions to acquire and carry on the business of Brilliant Earth, LLC. Brilliant Earth, LLC was originally incorporated in Delaware on August 25, 2005, and subsequently converted to a limited liability company on November 29, 2012. Brilliant Earth Group, Inc., the sole managing member of Brilliant Earth, LLC, consolidates Brilliant Earth, LLC and both are collectively referred to herein as "the Company". The Company designs, procures and sells ethically-sourced diamonds, gemstones and jewelry online and through 32 showrooms operating within the United States ("U.S.") as of June 30, 2023. Co-headquarters are located in San Francisco, California and Denver, Colorado. Basis of Presentation The unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and the requirements of the Securities and Exchange Commission (the "SEC") for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP can be condensed or omitted. These interim results are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2023, or for any other interim period or for any other future year. The condensed consolidated balance sheet as of December 31, 2022 has been derived from the audited consolidated financial statements of the Company, which are included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 (the "2022 Form 10-K"). In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments consisting only of normal recurring adjustments necessary to state fairly the financial position, results of operations and cash flows for the periods presented in conformity with U.S. GAAP applicable to interim periods. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2022, as disclosed in the 2022 Form 10-K. There have been no material changes or updates to the Company's significant accounting policies from those described in the audited consolidated financial statements included in the 2022 Form 10-K except for the updates noted below. Principles of Consolidation and Non-Controlling Interest The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiary, Brilliant Earth, LLC, which it controls due to ownership of the voting interest or pursuant to variable interest entity ("VIE") accounting guidance. All intercompany balances and transactions have been eliminated in consolidation. The non-controlling interest on the unaudited condensed consolidated statements of operations represents the portion of earnings or loss attributable to the economic interest in Brilliant Earth, LLC held by the Continuing Equity Owners. The non-controlling interest on the unaudited condensed consolidated balance sheets represents the portion of net assets of the Company attributable to the Continuing Equity Owners, based on the portion of the LLC Interests owned by such unit holders. As of June 30, 2023, the non-controlling interest was 87.6%. At the end of each reporting period, equity related to Brilliant Earth, LLC that is attributable to Brilliant Earth Group, Inc. and Continuing Equity Owners is rebalanced to reflect Brilliant Earth Group, Inc.'s and Continuing Equity Owners' ownership in Brilliant Earth, LLC. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Some of the more significant estimates include inventory valuation, allowance for sales returns, estimates of current and deferred income taxes, payable pursuant to the tax receivable agreement, useful lives and depreciation of long-lived assets, and fair value of equity-based compensation. Actual results could differ materially from those estimates. On an ongoing basis, the Company reviews its estimates to ensure that they appropriately reflect changes in its business or new information available. Fair Value Measurements Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. U.S. GAAP prescribes three levels of inputs that may be used to measure fair value: Level 1 Valuation based on quoted prices (unadjusted) observed in active markets for identical assets or liabilities. Level 2 Valuation techniques based on inputs that are quoted prices of similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not in active markets; inputs other than quoted prices used in a valuation model that are observable for that instrument; and inputs that are derived from, or corroborated by, observable market data by correlation or other means. Level 3 Valuation techniques with significant unobservable market inputs. The Company is required to disclose its estimate of the fair value of material financial instruments, including those recorded as assets or liabilities in its financial statements, in accordance with U.S. GAAP. At June 30, 2023 and December 31, 2022, there were no financial instruments (assets or liabilities) measured at fair value on a recurring basis. The carrying amounts of cash and cash equivalents, restricted cash, accounts payable and accrued expenses and other current liabilities approximate fair value due to their short-term maturities and were classified as Level 1. The carrying value of long-term debt, net of debt issuance costs, also approximates its fair value, which has been estimated by management based on the consideration of applicable interest rates (including certain instruments at variable or floating rates) for similar types of borrowing arrangements and were classified as Level 2. Recent Accounting Pronouncements The Company has considered all recent accounting pronouncements issued, but not yet effective, and does not expect any to have a material effect on the Company’s condensed consolidated financial statements.
