Sotheby’s will offer an 8.63-carat pink diamond at its upcoming jewelry sale in Geneva, where it could bring in up to $6 million.
The unmounted oval modified brilliant-cut, fancy-intense-pink, VS2-clarity, type IIa diamond will lead the November 11 High Jewelry auction, Sotheby’s said Tuesday. That event will directly precede the Sotheby’s Royal & Noble Jewels sale, also taking place in Geneva.
Between the two sales, the auction house will present a bevy of colored diamonds, gemstones and signed jewels from well-known design houses, including Cartier, Bulgari, Van Cleef & Arpels, and JAR.
Here are some of the other top items in the High Jewelry auction:
