Christie's to offer 15.49-carat Kashmir sapphire ring in June sale
Christie’s will place a 15.49-carat Kashmir sapphire ring into its June 9 sale, backed by SSEF and Gübelin reports calling it unheated royal blue.
A 15.49-carat Kashmir sapphire ring is set to anchor Christie’s Magnificent Jewels sale in New York on June 9, where the estimate runs from $1.2 million to $1.8 million. The cushion mixed-cut sapphire, mounted with round diamonds in platinum, is cataloged as an important sapphire and diamond ring, and the paperwork attached to it matters almost as much as the stone itself.
Two 2026 lab reports, from SSEF and Gübelin, identify the gem as Kashmir origin with no indications of heating. Gübelin describes the color as Royal Blue. In the rarefied world of colored stones, that combination is the sort of language collectors chase: origin, treatment status and color all line up to support the kind of price that puts a jewel firmly in the top tier of the market.
Kashmir sapphires have become mythologized because authenticated examples are scarce and the best stones carry a saturated, velvety blue that has long set the standard for sapphire color. Here, the center stone does the talking. The diamonds and platinum are there to frame it, not compete with it, which is exactly what separates exceptional colored-stone engagement rings from the more familiar diamond-center narrative. The appeal is not just size. It is the idea that the gem itself, with documented origin and no heating, is the luxury object.
Christie’s is pairing that ring with a broader sale built around blue. The house says the New York auction will include notable private collections and jewels by Bulgari, Cartier, David Webb, JAR, Tiffany & Co. and Van Cleef & Arpels. But the headline momentum belongs to two other stones at the top of the catalog: the 31.62-carat Azure Blue pear-shaped fancy blue diamond and a 5.04-carat fancy vivid blue diamond ring, each estimated at $8.5 million.
The June offering also comes with a useful benchmark. In October 2025, Christie’s sold a 16.58-carat Kashmir sapphire ring online for $1,016,000, showing that collector appetite for unheated Kashmir stones has held in the low- to mid-seven-figure range. This latest ring is slightly smaller but more visibly positioned as a statement lot, the kind of stone that turns an engagement ring into a collecting category of its own.
