blue diamond 7.64 caratPrices for blue diamonds continue to rise. At the Sotheby's auction in Geneva a 7.64 carat fancy intense blue cushion-shaped diamond mounted in yellow gold and platinum sold to an anonymous client for $8,034,503. That number sailed above the estimate of between $4-6 million, setting a new record price of $1,051,636 per for carat for a fancy intense blue diamond sold at auction. Sotheby's was the previous record holder with $796,178 per carat for a 3.17 carat fancy intense blue diamond in November 2009 in Geneva. Last May a 7.03 carat stone sold for $9.49 million.

Sotheby's says this is the largest cushion shaped stone of this color grading ever to appear at auction. The diamond is graded as a Fancy Intense Blue, Natural Colour, VVS2 Clarity, and comes with an additional GIA worksheet stating that the diamond may be Potentially Flawless after repolishing. The Sotheby's Spring Sales of Magnificent and Noble Jewels brought a total of $53,976,331, handily above pre-sale expectations of $32.4-46 million with most lots selling and more than 74 percent of the lots sold achieving prices in excess of their high estimate.
