It was estimated at between 35 and 55 million dollars: the blue diamond, codenamed Blue Moon, was sold by Sotheby’s in Geneva for a median figure, 48.5 million (45 million euro). It is not the maximum, but it’s a new world auction record for a diamond of this color. The Blue Moon was sold, in fact, for over $ 4 million per carat, an unprecedented level. The stone is one of the largest fancy vivid blue diamond in the world, and has a weight of 03.12 carats, perfect internally. He also beat the previous record, held by Graff Pink (24.78 carats), sold in 2010 for 46.2 million dollars. Sign, in short, that the fever for colored stones continues unabated: just remember that last year Zoe Diamond, another blue stone, it was sold in New York for 3.3 million per carat.
More generally, the auction of Magnificent Jewels and Noble Jewels has totalized 139 million, only slightly below the record for an auction of jewelry, set at Sotheby’s in Geneva in May. Among the pieces out, a ring with a superb Fancy Vivid Purple-Pink Diamond, sold for 13.9 million dollars, auction record for a diamond of this type. Even sapphires go very well. A ring with sapphireVery Fine and diamonds has more than doubled the pre-sale estimate, to 3.2 million. Even a brooch with ruby, sapphire and diamond Van Cleef & Arpels has exceeded expectations presale, passing from hand to 2.5 million, nearly five times its lowest estimate.
Of note is the tiara of diamonds, by Cartier, dated around 1909, sold for 799mila dollars, almost doubling its highest estimate. The tiara has an adventure story: was commissioned to Lady Allan from her husband, Sir Hugh Allan, and it survived at the famous naufragio of the Lusitania, together with its owner, in 1915.
