The biggest yellow diamond, a 100-carat one, was sold in Geneva for $16.3 million. A private buyer acquired the Graff Vivid Yellow at a Geneva jewellery sale in Sotheby's auction house. Reuters reported that it was a world record for the jewellery auction of a yellow diamond, according to David Bennett, the chairman of Sotheby's Switzerland.
The record on Earth is held by a stone found by a mining company in August 2007 in a North West province of South Africa. Before that, the Cullinan, which was found near Pretoria in 1905, was the largest cut diamond in the world at 530.20 carats, until it lost the record in 1985 to the Golden Jubilee.
