Christie's Kicks Off 2026 Jewelry Auctions With 10-Carat Diamond Centerpiece

Christie's opened 2026's jewelry calendar with "Jewels Online," a 156-lot online sale that began accepting bids on March 9 and runs through March 19, with in-person previews at the Rockefeller Center galleries in New York from March 16 to 18.

The sale's marquee lot is a 10.02-carat emerald-cut diamond ring signed by Tiffany & Co., carrying an estimate of $500,000 to $700,000. The stone's credentials are exceptional even by auction standards: it is classified as Type IIa, the chemically purest category of diamond, graded D color and Internally Flawless, and set in platinum. Type IIa diamonds represent a small fraction of all gem-quality stones, and a 10-carat example at this color and clarity grade rarely surfaces outside a major auction house.

Close behind it in the headline hierarchy is a pair of diamond stud earrings estimated at $300,000 to $500,000. Each stone is also Type IIa and D color, with VVS2 clarity, weighing 5.13 carats and 5.04 carats respectively. Together they offer the kind of matched pair that is genuinely difficult to assemble, since finding two stones of near-identical size and top grading at the same time requires either extraordinary luck or a very well-connected dealer.

The sale's colored-stone offering is anchored by a Kashmir Sapphire and Diamond Ring, estimated at $120,000 to $180,000. The sapphire weighs 4.74 carats. Kashmir origin commands a consistent premium at auction because production from the region's mines essentially ceased more than a century ago, making new supply impossible.

Among the signed lots, the grouping called "Stylish Jewels from a Distinguished Collector" brings 18 pieces to market, primarily by David Webb and Cartier, led by a Cartier Diamond 'Bamboo' Necklace estimated at $40,000 to $60,000. Hemmerle's multi-gem tassel earrings are estimated at $30,000 to $50,000, and the sale's broader roster includes pieces by Seaman Schepps, Van Cleef & Arpels, and Tiffany & Co.

Two lots formerly from the collection of Elizabeth Taylor add provenance weight to the lower price tiers: a Diamond and Gold Evening Bag estimated at $10,000 to $15,000, and a beaded ruby and diamond necklace and earring set estimated at $15,000 to $20,000. Property from the collection of Yvonne Kalman contributes seven lots, including a pair of Diamond Cluster Earrings estimated at $15,000 to $20,000.

The breadth of the sale, from a sub-$20,000 evening bag to a seven-figure diamond ring, reflects Christie's stated range across categories, with price points spanning $500 to over $100 million. What the Jewels Online format offers that a white-glove evening sale does not is accessibility: bidding is open online for ten days, and the Rockefeller Center viewing is available to anyone who wants to hold these pieces before committing. The auction closes March 19.
