The largest white diamond ever auctioned will go under the hammer in Geneva next week, as part of a sale by Christie’s that features two stones weighing more than 200 carats each.
Christened as “The Rock”, the 228.31 carat pear-shaped white diamond stone is roughly the size of a golf ball. It is expected to sell for up to $30 million, said the auctioneer.
“Often with these largest stones, they sacrifice some of the shape in order to keep the weight,” said Max Fawcett, the head of Christie’s jewellery department in Geneva.
He went on to add, “This is a perfectly symmetrical pear-shape form and …one of the rarest gems ever to be sold at auction.”
Mined in South Africa, “The Rock” was worn by its former owner as a Cartier necklace. The previous auction record for a white diamond was a 163.41 carat gem sold in 2017.
Christie’s is also selling a 205.07 carat yellow, cushion-shaped stoned named as “The Red Cross Diamond”; an unspecified portion of its auction proceeds will go to the Geneva-based International Committee of the Red Cross (ICRC).
