exceptional provenance, was a ring from the collection of Countess Mona Bismarck. Set with a magnificent step-cut emerald weighing approximately 9.50 carats within a double frame of circular-cut diamonds, the ring was sold for CHF 289,000 ($257,178). In the Mona Bismarck sale at Sotheby’s in May 1986, it was sold for just CHF 143,000. Signed period pieces sold well tonight, with a particularly high price achieved for a Fine Diamond Bracelet by Van Cleef & Arpels, circa 1950, which sold for CHF 661,000 ($588,217), more than three times its low estimate of CHF 180,000.
There were bidders competing for the piece, the winning bid coming from an anonymous collector bidding on the telephone. Today’s sale brings the 2007 total for Magnificent Jewels sold at Sotheby’s Switzerland to CHF 124,067,830 ($106,019,622) – the highest total for annual sales of Jewellery in Switzerland since 1995.
