GIA Certified 5.89 Carat Triangular Cut No Heat Green Sapphire Diamond Ring

About the Item

GIA-certified color-change sapphire and diamond ring featuring a rare, unheated triangular mixed-cut sapphire that shifts from green to grey-purple—an extraordinary natural phenomenon. Unlike the majority of sapphires on the market, over 90% of which are heat-treated, this untreated gemstone holds exceptional value. The center stone is encircled by a halo of brilliant diamonds, with additional diamond accents along the shank totaling 0.86 carat and an intricately crafted under-gallery. Expertly set in 18K yellow gold. Accompanied by three certifications (GIA, AIG, and GAI) along with a full appraisal report.
