Watch live as the largest diamond seen throughout auction history goes on sale at Christie’s auction house.
The 228.31 carat white diamond, named “The Rock”, could sell for at least $30 million. It will be auctioned as part of the “Magnificent Jewels” event in Geneva on Wednesday (11 May).
The diamond is accompanied by a letter from the Gemological Institute of America which says that the jewel is the “largest existing D-to-Z colour range pear-shaped diamond” their laboratory has graded.
