The most expensive diamond, dubbed the “ultimate emerald-cut diamond”, sold for $22.1 million at Sotheby’s Auction of Magnificent Jewels on 21 April. Weighing in at 100.20ct, the size and exceptional quality of this extraordinary D color, Internally Flawless, Type IIA stone, places the diamond in a record-breaking league of its own.
Not only is it the largest perfect emerald-cut diamond to ever be offered at auction, the giant gemstone is now also the first 100-plus carat perfect diamond to be sold at a jewelry auction in the US. The remarkable stone also achieved the highest price for any colorless diamond auctioned in New York.
In the last 25 years, only six perfect diamonds weighing more than 100ct have sold at auction, with five of them going under the hammer at Sotheby’s in Geneva, Hong Kong and now New York.
While news of the results of the Magnificent Jewels Sale was naturally dominated by the spectacular gemstone, a number of other lots helped push total sales to $65 million, setting a new record for Sotheby’s New York.
