An impeccably clean diamond weighing 101.73 carats last week was sold at Christie's auction in Geneva for $ 23.5 million, the Swiss media reported.
The Gemological Institute of America (GIA) awarded the "white" diamond with the highest color category (D) and the highest degree of purity IIA (this category includes only about 2% of the world's jewelry diamonds).
The diamond was discovered on the mines in Botswana, it was polished for 21 months, and the original weight of the raw stone was 236 carats.
The new owner of the pear-shaped jewelry, which will henceforth be called "Winston Legacy", was American jeweler Harry Winston.
