More than 200 lots of diamonds, rare gemstones, and signed designer jewels brought $27.6 million at Christie’s New York sale of Important Jewels on June 16.

The top lot, a cushion-cut Kashmir sapphire of 21.71 carats, realized $4.2 million. Signed by Cartier, flanked on both sides by trapeze-shaped diamonds, and mounted in platinum, the ring was part of the collection of Margaret Adderley Kelly, which saw a 100% sell-through totaling just shy of $10 million.

Sotheby’s  “Magnificent Jewels and Noble Jewels” in Geneva will offer jewels with sought-after royal provenance along with other impressive gems such as a Kashmir sapphire weighing 27.54 carats (Est. $3.0-6.0 million) and the 8.62-carat “Graff Ruby” (Est. $6.8‑9.0 million), as well as exquisite vintage pieces by Cartier and Bulgari.

In total, the 470 assembled lots of the November 12 sale are expected to bring in excess of $62 million.

Bonhams raked in a total of £4.2 million ($7.1 million) at its fine jewelry sale on April 30 in London, on the back of its top three lots doubling and tripling their estimates.

The star of the sale was an exquisite Colombian emerald ring, of 10.49 carats and set between diamond shoulders, that brought $610,039, or more than triple its high estimate.

A new world auction record price per carat for any sapphire was set tonight at Sotheby’s New York, when an Exceptional Platinum, Kashmir Sapphire and Diamond Ring sold for $5,093,000 / $180,731 per carat (est. $4/5 million). The square emerald-cut Kashmir sapphire weighing 28.18 carats is one of the finest sapphires ever to appear at auction, described by the American Gemological Laboratories (AGL) as “a gem of singular importance.”
