The Graff

The Graff Pink, a rare 24.78 carat pink diamond, once owned by American celebrity jeweller Harry Winston, has been described as "one of the greatest diamonds ever discovered". The diamond was mounted in a ring and was sold by Sotheby's auctioneers 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. After selling for US $46 million it became the most expensive single jewel ever sold at auction.

The diamond was graded by the Gemological Institute of America as "Fancy Intense Pink" which is a high colour rating for pink diamonds and has been assessed as type 2a, 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 American celebrity jeweller Harry Winston to a private collector, who owned it up until 2010, until it was sold at auction in 2010.
