The Brilliant Earth Story: The Engagement Ring With a Clear Conscience

The company began, fittingly, with an engagement. As co-founder Beth Gerstein told it, shopping for her own ring in the mid-2000s she asked jewellers a simple question — where did this diamond come from? — and discovered that almost nobody could answer. For a purchase meant to symbolize love, the industry's supply chain was a shrug, and headlines about conflict diamonds had given that shrug a dark edge.

Gerstein and her Stanford classmate Eric Grossberg founded Brilliant Earth in 2005 to be the answer: jewellery from traceable, responsibly-sourced origins, recycled precious metals, and later lab-grown options — sold with the origin story attached to the stone. The name itself does double work, promising both sparkle and planet. What the traditional trade treated as an awkward question became their entire shop window.

It worked because the timing of hearts had changed: a generation that asked where its coffee and sneakers came from was never going to stop asking at the jewellery counter. Brilliant Earth grew from a San Francisco showroom into a publicly listed company, and the incumbents scrambled to add their own traceability pages. That is the mark of a story well aimed — when your competitors are forced to answer the question you taught customers to ask.
