Largest and most valuable blue diamond to come to auction at Sotheby's Hong Kong
(VOVWORLD) - It's the largest and most valuable blue diamond to ever come to auction. And, it's a recent discovery.
The more than 15-carat De Beers Cullinan Blue diamond was mined in 2021 at South Africa's Cullinan Mine, one of the few sources in the world for extremely rare blue diamonds.
It will be offered in a single-lot auction at Sotheby's Hong Kong this April and is estimated to be valued in excess of 48 million USD.
The Gemological Institute of America (GIA) graded the diamond a Fancy Vivid Blue - the highest possible color grading according to Sotheby's, awarded to no more than 1% of blue diamonds.
