GENEVA - This evening Sotheby’s Geneva sold the most important emerald and diamond tiara to have appeared at auction in over 30 years for CHF 11,282,500 /$12,736,927, the highest price ever achieved for a tiara at auction. Six bidders competed for the magnificent and extremely rare emerald and diamond tiara, circa 1900, which was formerly in the Collection of Princess Katharina Henckel von Donnersmarck (est. CHF 4.6-9.2 million/$5-10 million [lot 443]); the price it fetched also represented an auction record for a piece of emerald jewellery. The total for the entire sale of Magnificent and Noble Jewels was CHF 78,944,900/$89,121,687 (est. CHF 41.9 - 69 million / $ 47.3 – 77.9 million).
Commenting on this evening’s sale, David Bennett, Chairman of Sotheby’s Jewellery Department for Europe and the Middle East, said: “Sotheby’s was honoured to be able to offer perhaps the grandest piece of jewellery to come to sale in over 30 years and the market responded with enthusiasm. This evening’s results, across the board -- in Noble Jewels, diamonds, coloured gemstones, and pieces signed by the world’s greatest jewelers – show the extraordinary appetite among connoisseurs for rarity, quality and provenance.”
International jewellers Leviev outbid four underbidders to purchase a superb fancy
intense pink diamond, weighing 10.99 carats, for CHF 9,602,500/$10,840,358,
the third highest price for a pink diamond (the ninth highest price for a diamond at
auction). Pink diamonds have been prized for their rarity and spectacular beauty
ever since they were first discovered in the mines of India centuries ago. This superb
stone, mounted as a ring, has been graded “fancy intense pink”, natural colour and VS1 clarity by the Gemological Institute of America (GIA). It has been further assessed to be part of a very rare subgroup of diamonds known as type IIa and comprising less than 2% of all of the world’s gem diamonds. Estimated at CHF 8.3-14.8 million ($9-16 million [lot 491]), this stone was offered for sale from a private collection and has not appeared on the market for more than 30 years.
The total Sotheby’s achieved for Noble Jewels, including the tiara, was CHF 19,618,300/$ 22,147,295 (against pre-sale estimates of CHF 7,282,000-13,203,500/$8,220,723 - 14,905,563).
