A pink diamond took the top spot at a recent jewelry sale at Sotheby’s in Geneva, raking in CHF 4.5 million ($5.4 million) and leading a strong showing of colored stones.
The unmounted oval modified brilliant-cut, 8.63-carat, fancy-intense-pink, VS2-clarity, type IIa diamond sold at the higher end of its CHF 3.3 million to CHF 5 million ($4 million to $6 million) estimated range. In total, the November 11 High Jewelry auction brought in CHF 32.6 million ($39.2 million).
Many lots at the sale went for well above their high estimates, including a Cartier Art Deco gem-set and diamond tutti frutti brooch, which scored CHF 128,000 ($153,626), almost 10 times its CHF 13,000 ($15,603) presale price. Meanwhile, a Boucheron diamond tiara estimated at CHF 35,000 to CHF 50,000 ($42,007 to $60,015) garnered CHF 166,400 ($199,714), more than triple its upper valuation.
