Kashmir sapphire ring leads Heritage Auctions’ record $9.7 million jewelry sale
A 6.59-carat Kashmir sapphire ring fetched $906,250, showing how origin, rarity and a clean setting can turn a jewel into an heirloom.
The ring that set the tone for Heritage Auctions’ spring jewelry sale did so with proof, not just sparkle: a 6.59-carat Kashmir sapphire ring brought $906,250 in Dallas, turning a $300,000 to $600,000 estimate into a result that more than tripled the low end and topped the high end by more than $300,000.
What made the piece feel legacy-worthy was the detail. The sapphire was octagonal-shaped and mounted in platinum with trapezoid-shaped diamonds weighing about 1.00 carat total. Heritage listed the center stone as Natural Corundum, Sapphire, Classic™ Kashmir Origin, with no gemological evidence of heat. A GIA report dated January 13, 2026 also gave the stone Kashmir origin and no indications of heating. In colored stones, that combination of origin, documentation and untreated status is the sort of paper trail collectors remember when they are buying for the next generation, not just the next auction.
Heritage’s Spring Fine Jewelry Signature® Auction #5579, held May 4, 2026, finished at $9,713,640, the highest-grossing jewelry auction in the company’s history. That total edged past Heritage’s previous jewelry-auction record of $9,220,693 set in September 2025. Jill Burgum, Heritage’s executive director of fine jewelry, said there was “strong, confident bidding at every level” and that “excitement built from the start.”
The Kashmir ring was not the only stone pulling attention. Another Kashmir sapphire in the sale, a 10.01-carat cushion-shaped stone, realized $106,250. A 20.03-carat Cartier fancy intense yellow diamond ring sold for $625,000, while a 6.45-carat faint pink diamond brought $562,500 and a 4.93-carat light pink diamond reached $500,000. Together, those results showed that demand in the room extended well beyond white diamonds into stones with color, provenance and a clear identity.
That is the real lesson in the $906,250 result. A jewel becomes heirloom-worthy when its beauty is reinforced by origin, rarity, symbolism and setting. The Kashmir sapphire ring had all four, and Heritage’s record day showed that buyers still pay for a story they can verify.
