Heritage’s spring sale spotlights rare fancy diamonds, Kashmir sapphires, Cartier duck brooches

The Cartier duck brooches will bring the levity, but Heritage’s spring fine jewelry sale is really a lesson in where prestige money is headed: toward rare fancy-color diamonds, Kashmir sapphires, and signed jewels with names that still carry weight at the top of the market. Scheduled for May 4, 2026, in Dallas, the auction spans lots 55001 through 55440, with more than 400 lots offered through live, online, telephone, fax, and mail bidding. Preliminary viewing is set for April 29 and 30 by appointment.

At the center is a Cartier ring set with a 20.03-carat fancy intense yellow diamond, a cut-cornered rectangular modified brilliant-cut stone graded VVS2. Heritage has placed it at $600,000 to $800,000, with a $500,000 reserve, a telling spread that shows just how much confidence the house is putting in vivid color and size together. Fancy-color diamonds remain a rarified category, and that scarcity is part of the appeal: in a field where white diamonds still dominate the market, a properly saturated yellow stone reads as both trophy and talking point.

The rest of the top tier pushes the same message in different registers. There is a Kashmir sapphire ring centered on a 6.59-carat octagonal stone flanked by trapezoid diamonds, plus another ring centered on a 10.01-carat Kashmir sapphire. There is also a Van Cleef & Arpels ring with a 6.88-carat fancy intense yellow VS1 diamond, an unmounted 6.45-carat faint-pink VS1 diamond, an unmounted 4.93-carat light-pink VS1 diamond, a 7.50-carat F, VVS2 diamond ring, and an emerald-cut 4.71-carat F, VS1 diamond ring. The mix suggests that collectors are still rewarding stones with clear provenance, strong grades, and color that is either vivid or delicately impossible.

The sale’s most charming interruption is also one of its sharpest signals. A Cartier duck brooch pair will pull attention, as will a Van Cleef & Arpels scarecrow brooch in enameled 18k gold with diamonds and sapphires, and a diamond-studded Victorian lorgnette. Then there is the De Beers hourglass, circa 2000, marked De Beers and filled with more than 2,000 natural rough octahedral diamonds totaling about 36 carats, mounted in gold-plated brass and glass and estimated at $6,000 to $8,000. Heritage, which calls itself the largest collectibles auctioneer and the third largest auction house in the world, is making a clear pitch: the strongest spring money still chases blue-chip stones, but it also has room for whimsy when the whimsy comes from Cartier.
