The De Beers Blue Diamond was discovered at the Cullinan Mine in South Africa in 2021, one of the few sources worldwide for scarce blue diamonds. Over the past year, De Beers has worked with its partner, Diacore, one of the most experienced master diamond cutters, to cut and polish the extraordinary rough diamond and bring The De Beers Blue to life.
Recently at Sotheby’s Hong Kong, a significant new benchmark for the diamond market was set, as the extraordinary ‘De Beers Blue’ – a 15.10 step-cut Fancy Vivid Blue diamond, the largest of its kind ever to appear at auction – sold for HK$451 million / US$57.5 million.
