Rare D-Flawless Diamond Captivates at 100 Carats

Earlier this year to celebrate the first anniversary of its New Bond Street salon, Sotheby’s Diamonds unveiled an exceptionally rare 102.34-carat, white diamond - and the stone has now found a buyer. The only known round brilliant-cut diamond over 100 carats that is perfect according to every critical criterion, the stone was purchased for a price per carat, which far exceeds that for any colourless diamond sold at auction.
