The Winston Blue is the name given to what was the largest flawless vivid blue diamond bought by Harry Winston, Inc. (a wholly owned subsidiary of The Swatch Group from January 2013) on May 15, 2014, from an anonymous person for $23.8 million at Christie's Geneva Magnificent Jewels sale. The approximately $1.8003 million per carat price paid for the 13.22-carat diamond is a world record for a blue diamond. Harry Winston, Inc. had also bought a 101.73-carat colorless diamond named Winston Legacy at Christie's Geneva jewelry auction in 2013. The American luxury jeweler had then paid $26.7 million for the colorless diamond ($254,400 per carat), which is a world record for the highest price paid per carat for a colorless diamond.
