Brilliant Earth sells certified loose diamonds you can filter by shape, cut, clarity, carat and origin, graded by GIA, IGI or GCAL. Its Beyond Conflict Free sourcing standard is the brand's main draw for buyers who care where the stone came from. Founded in 2005, it ships internationally and is built around picking the diamond first, then the setting.
