Brilliant Earth

Brilliant Earth

Brilliant Earth was launched in 2005 by Beth Gerstein and Eric Grossberg with a thesis that lab-grown and traceable natural diamonds could compete with legacy jewelers on storytelling as much as carats. The company positions itself at the intersection of luxury and ethical consumption, selling engagement rings, wedding bands, and fine jewelry through its e-commerce platform and a growing network of showrooms across the United States. The firm sources diamonds from mines that meet its Beyond Conflict Free standards — verified through third-party audits — and pairs mined stones with lab-grown alternatives manufactured in controlled facilities. Its product mix spans bridal jewelry, which generates the bulk of revenue, alongside expanding categories in fashion and men's jewelry. The company competes directly with Signet-owned chains (Jared, Kay) and independent jewelers by eliminating wholesale intermediaries. It operates showrooms in cities including San Francisco, New York, Los Angeles, and Chicago, where customers examine stones in person before purchasing online. Brilliant Earth completed its initial public offering in September 2021, listing on Nasdaq under the ticker BRLT, backed by a growth equity investment from Mainsail Partners earlier in its history. As a public reporting company, detailed financials are available through SEC filings rather than typical family office or private asset manager disclosures. The firm's physical retail footprint stood at over 30 showrooms as of mid-2023, and it has continued expanding into new US markets alongside a selective international presence. The structural differentiator is its hybrid direct-to-consumer model: an e-commerce backbone with physical showrooms that carry minimal inventory — customers view samples and place orders for custom pieces. This asset-light approach to physical retail sets it apart from traditional jewelers burdened with high carrying costs, while the dual-mined-and-lab-grown product line hedges against consumer sentiment shifts on diamond origin preferences. As co-founders, Gerstein and Grossberg both remain actively involved in the business post-IPO.
