Kashmir sapphire ring leads Heritage Auctions’ record jewelry sale
A 6.59-carat Kashmir sapphire ring stunned Dallas, soaring to $906,250 and helping Heritage set a new jewelry auction record.
A 6.59-carat Kashmir sapphire ring did more than lead Heritage Auctions’ spring fine jewelry sale in Dallas. It nearly tripled its $300,000 high estimate, selling for $906,250 and showing how fiercely collectors still compete for colored stones with a verifiable origin story.
The ring’s appeal began with the center stone itself: an octagonal Kashmir sapphire, set in platinum and framed by trapezoid-cut diamond side stones. That combination mattered. The octagonal cut gave the sapphire a crisp, architectural profile, while the diamond shoulders kept the look refined rather than flashy, letting the stone’s velvety texture and cornflower-blue color remain the focus. In a market crowded with larger but less distinctive gems, rarity and proportion carried the day.
Kashmir sapphires continue to command a premium because their supply is finite in a way that matters to collectors. Heritage said the original mines were discovered in the 1880s in the remote Zanskar Range of the Himalayas and were depleted within just a few decades, leaving no new source entering the market. That scarcity, paired with strong provenance, is exactly what sends well-heeled buyers into the bidding war that unfolded here.
“There was strong, confident bidding at every level, not just for the headline pieces, and that kind of energy is what drives a result like this,” said Jill Burgum, Heritage Auctions’ executive director of fine jewelry. The sale, conducted with floor, telephone, internet, fax and mail bidding, brought in $9,713,640 in total, the highest jewelry-auction total in Heritage’s history and a sharp jump from the company’s previous record of $9,220,693 in September 2025.
The numbers suggest the market still rewards jewels that offer more than size alone. A 20.03-carat fancy intense yellow diamond Cartier ring brought $625,000, and a 6.45-carat faint pink diamond realized $562,500, but the Kashmir sapphire outperformed both because it combined origin, color, shape and mounting in a single, highly legible package. For collectors and engagement-ring buyers alike, the message was plain: the colored stones that still earn real premiums are the ones with unmistakable provenance, elegant cutting and a setting that knows when to step back.
