The biggest diamond ever sold at auction has been snapped up for £25million, disappointing experts would thought the 163-carat whopper might go for twelve million more.
The 163.41-carat diamond, suspended from an emerald and diamond necklace called The Art of Grisogono, sold tonight to an anonymous telephone bidder at the Christie’s autumn jewel auction in Geneva, Switzerland.
This marks ‘a new world-record price for a D colour diamond at auction,’ Rahul Kadakia, auctioneer and head of Christie’s international jewels division said.
D is the highest colour grade attributed to a diamond, indicating that the stone is completely colourless, and thus extremely rare.
With a drawn-out round of rapid-fire bidding starting at £15million, the necklace was finally sold to a telephone bidder, who wished to remain anonymous.
