The cushion-shaped stone weighing 103.83 carats\nThis magnificent stone is the largest D colour, Internally Flawless diamond ever to be offered at auction. Only three other diamonds of perfect colour and purity weighing over 100 carats have been sold at auction internationally and Sotheby’s Geneva has had the privilege of selling each of them. These spectacular diamonds are presently the three most valuable gemstones ever to have been sold at public auction.\n\nThis diamond, which was discovered in the famous Premier Mine in South Africa, has immense presence and beauty. It is exceptional not only for its size, colour and purity but also because it has beautiful proportions and exhibits the cutter’s skill at its height. The process of planning, designing and cutting the rough crystal, which took place in Johannesburg and New York, took over eighteen months to complete.\nIts classic cushion-shaped form is reminiscent of so many famous and historic diamonds such as:- the "Cullinan II", 317.40 carats, presently in the Imperial State Crown of Great Britain; the "Regent", 140.50 carats, presently in the Louvre Museum, Paris; and the "Queen of Holland", 135.92 carats, owned privately.\nOnly very few "D" colour, Internally Flawless diamonds of over 100 carats exist in the world today and they truly rank amongst the earth’s greatest treasures.\nThis exceptional gemstone has been exhibited in the Smithsonian’s National Museum of Natural History in Washington during the month of September 2003, in an exhibition entitled "The Splendor of Diamonds"; this is a fitting tribute to such a rare and splendid diamond.\nThe appearance of such a diamond at auction is a very special event. The successful buyer will have the additional privilege of naming this unique stone which will certainly take its place among the most famous diamonds of the world.
