A key highlight of the Sotheby’s Geneva Magnificent Jewels sale is going to be the Sun-Drop Diamond - a 110.03 carat VVS1 stone graded by the Gemological Institute of America (GIA) as Fancy Vivid Yellow, the highest colour grading for a yellow diamond. The sale is slated for November 15, 2011.

The rough for the Sun-Drop Diamond was discovered in South Africa in 2010, and was cut and polished by Cora International, one of the world’s leading manufacturers of exceptional diamonds. The Sun-Drop Diamond ranks as the largest known pear-shaped fancy vivid yellow diamond in the world and carries an estimate of $11-15 million. It was previously exhibited this year at London’s Natural History Museum.

Commenting on the forthcoming sale of the Sun-Drop Diamond, David Bennett, Chairman of Sotheby’s Jewellery Department in Europe and the Middle East and Co-Chairman of Sotheby’s Switzerland said: “This stone has immense presence and is truly stunning. It is also one of the largest diamonds ever to have appeared at auction. It is an honour to have been chosen by Cora International to present it to the market.”

The Sun-Drop Diamond was presented at Sotheby’s Hong Kong on 6th October and will be showcased in an international tour at various Sotheby’s locations before its sale in Geneva on 15 November.
