Brilliant Earth was co-founded by Beth Gerstein and Eric Grossberg, who met at Stanford University. Beth experienced firsthand, with her fiancé Alex, the challenge of finding a conflict free engagement ring that represented her values. Eric, through his research at Stanford, had become impassioned with the idea of responsibly-sourced jewelry, andits ability to be an effective tool for social change in gem communities. Together, Eric and Beth founded Brilliant Earth in 2005.
