GENEVA.- Sotheby's Geneva announces that it will present three exceptional diamonds in its 13th of May 2014 Auction of Magnificent Jewels and Noble Jewels.

Among these treasures, the historical Victory Diamond, was named in honour of the allied victory in World War II, a step-cut diamond weighing 31.34 carats. The rough was discovered in 1945 in the African “Woyie River” and was then the largest alluvial rough diamond ever found, weighing a massive 770 carats. In the early 1950s, thirty diamonds were cut from the rough, the largest gem being the Victory Diamond.

The stone has been graded by the GIA as “D” colour and Potentially Flawless; additionally it is “Type IIa”: a rare subcategory of diamonds which are chemically the purest of all diamond crystals and often have extraordinary optical transparency. The Victory Diamond formerly belonged to Florence Gould, celebrated as one of the truly great collectors of jewellery of the 20th Century. Est. CHF 4,430,000 – 7,100,000 (HK$ 38,600,000 – 62,400,000; US$ 5,000,000 - 8,000,000)

Also on display in Hong Kong will be the Graff Vivid Yellow, a sensational daffodil yellow diamond weighing 100.09 carats, mounted as a ring. Of exceptional beauty and extraordinary fire and brilliance, this gem is among the largest Fancy Vivid Yellow diamonds in the world. Est. CHF 13,250,000 – 22,250,000 (HK$ 116,500,000 - 194,000,000; US$ 15,000,000 – 25,000,000).

A third exquisite piece completes the trio of rare stones leading the selection of Geneva highlights in Hong Kong: a Spectacular Diamond Ring by Graff, set with a round brilliant-cut diamond which at 103.46 carats is one of the largest known round diamonds.
