Name: Blue Moon Diamond. Characteristic signs: is one of the largest deep blue diamond known. Address: Sotheby’s, Geneva. This exceptional diamond will star Magnificent Jewels and Noble Jewels auction on November 11. It is a very unusual stone weighs 12.03 carats and was ranked Fancy Vivid Blue, the degree of color more intense blue diamonds, by Gemological Institute of America (GIA). The the quality of cushion-cut is impeccable, and was declared Internally Flawless. The only flaw? The price: the estimate is between 35 and 55 million dollars. Note that it is a value of affection: between minimum and maximum there are 20 million dollars of difference, an impressive figure. “The great enthusiasm tried last year following the discovery of a blue diamond of 29.62 carats rough at the Cullinan mine in South Africa is completely justified,” glosses David Bennett, chairman of Sotheby’s to the Jewellery Division. “With a weight of 12.03 carats after cut, the Blue Moon is a stunning stone for color purity and form. For me, blue is the most magical and mysterious of all the colors of diamonds and therefore today Blue Moon ranks among the most famous gems in the world”. The enthusiasm, given the auction price, is justified. Federico Graglia
