DALLAS, TX.- A spectacular 6.59-carat Kashmir sapphire ring that realized $906,250 led Heritage’s May 4 Spring Fine Jewelry Signature® Auction to $9,713,640, marking the highest-grossing jewelry auction in the company’s history. The milestone result comes just over seven months after Heritage announced its previous record for a jewelry auction — $9.2 million in September 2025 — underscoring sustained momentum and robust demand for rare, high-quality jewels.

“This was one of those auctions where you could feel the excitement building from the start,” says Jill Burgum, Heritage’s Executive Director of Fine Jewelry. “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.”

Leading the auction was a platinum ring featuring a 6.59-carat octagonal-shaped Kashmir sapphire. The ring’s $906,250 result surpassed its high pre-auction estimate by more than $300,000. Renowned for their velvety texture and cornflower blue hue, Kashmir sapphires hail from the high-altitude Zanskar Range of the Himalayas and are among the most coveted gemstones in the world. The Kashmir stone at the center of this ring presents royal blue in a particularly pure expression, with American Gemological Laboratories denoting the example as Classic Kashmir Origin. Another Kashmir sapphire, a 10.01-carat cushion-shaped stone set in a diamond-studded ring, also performed well, realizing $106,250.

Another top lot was the Cartier fancy intense yellow diamond ring that sold for $625,000. The platinum and 18k gold stunner features a 20.03-carat stone as its showstopping centerpiece. Two other fancy yellow diamonds also saw exceptional results: a Van Cleef & Arpels fancy intense yellow diamond ring that brought $156,250 and a fancy yellow diamond ring that sold for $93,750. Only 1 in 10,000 diamonds has a fancy color, making these stones some of the rarest on Earth.

Yellow wasn’t the only diamond color that caught bidders’ attention. Rounding out the colored diamond highlights were a lovely 6.45-carat faint pink diamond that sold for $562,500 and a 4.93-carat light pink diamond that realized $500,000. Other diamond standouts included an 18k white gold ring with a 12.90-carat round diamond that brought $168,750, an 11.40-carat diamond ring that sold for $156,250, an Art Deco diamond necklace that realized $90,625, a 4.81-carat diamond ring that sold for $87,500 and a 4.55-carat diamond ring that realized $71,875.

The auction also brought together an impressive selection of colored gemstones, many of them notable in size and quality. Among the highlights was an extraordinary 100.31-carat Paraiba-type tourmaline that sold for $275,000. Exhibiting the vivid, neon-charged saturation that has come to define copper-bearing tourmaline, the pear-shaped stone radiates an unmistakable internal glow. Another Paraiba-type tourmaline, a 28.17-carat cushion-shaped stone set in a platinum ring, realized $100,000.

Among the other colored gemstone standouts were a 36.96-carat sapphire ring that brought $175,000 (more than 11 times its high pre-auction estimate), a pair of Colombian emerald earrings that sold for $75,000 (five times their high pre-auction estimate), an 8.50-carat Ceylon sapphire ring that realized $68,750 (more than six times its high pre-auction estimate) and a 17.48-carat Colombian emerald ring that sold for $65,625 (almost twice its high pre-auction estimate).

Other highlights included a pair of Van Cleef & Arpels 18k gold bracelets that realized $112,500 and a Van Cleef & Arpels necklace that brought $87,500.

“While the auction’s top lots were certainly exciting,” Burgum says, “what really surprised us all was the sheer volume of bidding wars. There really were no ‘sleeper’ lots. The audience was hungry and aggressively bidding.”
