In November 2010, a rare pink diamond smashed the world record for a jewel at auction, selling for more than $46 million to well-known London jeweler Laurence Graff. Four bidders competed for the pink diamond, which was last sold 60 years earlier by New York jeweler Harry Winston. The seller chose to remain anonymous. The 24.78-carat ‘‘fancy intense pink’’ diamond immediately became known as ‘‘The Graff Pink.’’
