The Graff Pink, a rare 24.78 carat pink diamond, once owned by Harry Winston, has been described as “one of the greatest diamonds ever discovered”.
The diamond, mounted in a ring, was sold by Sotheby’s in Geneva, Switzerland on 16 November 2010. Before its sale, the stone was expected to enter the list of the top ten most expensive diamonds in the world; on selling for US $46 million (£29 million) it became the most expensive single jewel ever sold at auction.The gem is classified by the GIA as “fancy intense pink”—a high color rating for pink diamonds—and has been assessed as Diamond type IIa, placing it in the top two per cent of the world’s diamonds.
The early history of the diamond is not clear. It was sold in the 1950s by Harry Winston to a private collector, who owned it up until 2010, when it was sold at auction. Despite its rarity, the diamond was unnamed for all this time. The diamond is emerald cut with rounded corners, and is mounted on a platinum ring with two flanking shield-shaped diamonds.
The pre-sale estimate for the diamond was US $27 million to US $38 million (£17 million to £24 million). The diamond was shown around the world prior to the auction in Geneva. It sold for US $46 million (£29 million), making it the most expensive single jewel ever sold at auction.
It was bought by diamond dealer Laurence Graff, of Graff Diamonds, who named it Graff Pink.
