The sale had a number of exceptional pieces which resulted in excellent hammer prices.

One of the sale’s highest value performers was a ruby and diamond bracelet by Van Cleef & Arpels. Dating from the late Deco period, the bracelet is set with three rectangular-shaped emerald-cut Burmese rubies and flanked by half-moon-shaped diamonds.  Following bidding on the telephone, online and in the salesroom, it eventually went under the hammer for $504,500.

Another Art Deco lot also captured buyers’ attention and created a bidding frenzy.  Dated circa 1925, the emerald and diamond bracelet by Tiffany & Co eventually sold for $187,500. The bracelet features a cushion-shaped cabochon Colombian emerald, weighing approximately 8.30 carats, flanked by similarly cut Colombian emeralds, weighing approximately 7.50 and 6.90 carats.  

Among the top-performing lots were two impressive diamond fringe necklaces weighing a total of 152.50 carats along with a 23.13 emerald-cut diamond ring – all signed by Harry Winston. 

These belonged to the Olympic gold medalist Katherine Domyan. The first of her diamond necklaces, with a total diamond weight of 86.30 carats, sold for $492,500. The second, with a total diamond weight of 66.20 carats, sold for $324,500.

Another two Harry Winston lots belonging to Katherine Domyan which caught the eye of buyers were a 23.13 carat emerald-cut diamond ring, which sold for $444,500 against its pre-sale estimate of $250,000-$350,000, and a pair of diamond earrings which sold for $187,500.
