A heart-shaped diamond pendant was the top seller at the latest Bonhams New York jewelry auction, exceeding its high estimate and fetching $343,400.
The necklace bearing the 10.22-carat, D-color, VVS2-clarity diamond carried an upper price tag of $250,000 at the December 9 New York Jewels sale, Bonhams said Tuesday. In total, the 195-lot auction garnered $4.3 million, with 82% of items on offer finding buyers. Auction participants snapped up jewels from designers including Bulgari, Cartier, David Webb, Harry Winston, Tiffany & Co., and Van Cleef & Arpels.
She particularly singled out the “strong result for the private estate of the late Cortney Beebe.” Beebe, who died of breast cancer in August, was a cofounder of the Cortney and Kevin Beebe TNBC Research Fund, which benefits the Hospital of the University of Pennsylvania Medical Center, Breast Cancer Center. Beebe’s husband Kevin is donating the sale’s proceeds to the fund.

– A cushion-cut, 10.64-carat, F, VS2 diamond on a ring brought in $267,200, within its estimated range.
– This ring boasts an emerald-cut, 10.63-carat, H, VS2 diamond center stone between two tapered baguette-cut diamonds. It garnered $254,500, smashing its $190,000 high estimate.
– Centering a cushion-cut, 16.48-carat, fancy-yellow, VS2 diamond, this ring sold for $203,700, just beating its $200,000 top presale price.
