GIA Certified Ceylon No-Heat Sapphire & Diamond Ring | 13.01ct | 18k White Gold | 9.9g | Size 5.5

“No heat” is the most coveted designation in the sapphire world — it means the stone has never been subjected to heat treatment, the industry-standard process used to enhance color and clarity in the vast majority of sapphires on the market. A GIA-certified no-heat Ceylon sapphire of 13.01 carats is extraordinarily rare: Ceylon (Sri Lanka) produces some of the world’s finest sapphires, and at this carat weight with documented natural origin, this stone belongs to a category that serious collectors and investors actively seek. The deep blue oval-cut stone is framed by 16 round brilliant-cut white diamonds, all set in 9.9 grams of 18k white gold that amplifies the sapphire’s cool, velvety color. Pre-owned, size 5.5, in very good condition — with GIA certification confirming its untreated status. A generational piece.
