Hong Kong’s most impressive high jewellery auctions of 2022 – and highlights to watch out for, as Christie’s sells Rosamund Kwan’s stunning US$12.8 million collection featuring Cartier and Bulgari
- The Williamson Pink Star diamond was sold for US$58 million at Sotheby’s Hong Kong – the second most valuable jewel ever sold at an auction behind the record-breaking US$71.2 million CTF Pink Star
- Rosamund Kwan’s 51 vintage gems by the likes of Cartier, Van Cleef & Arpels, Bulgari and Buccellati will go under the hammer, as will a sought-after gold Tiffany & Co. piece
Demand for ultra-upscale gems has remained resilient, as shown by the strong sales at Hong Kong’s live high-end jewellery auctions.
Hong Kong’s autumn live jewellery auction season this year was kicked off with the spectacular sale of the Williamson Pink Star, an 11.15-carat, cushion-shaped, fancy vivid pink and internally flawless diamond, in early October. After frenzied bidding, a private buyer in the United States secured the pink diamond for US$58 million. The hammer price makes the Williamson Pink Star the second most valuable jewel or gemstone ever sold at an auction, just behind the record-breaking 59.60-carat CTF Pink Star, which went for US$71.2 million in 2017. The Williamson Pink Star also established a world record price per carat (US$5.18 million) for any diamond or gemstone.
At the Poly Auction Hong Kong’s autumn sale, also held in October, which marked the 10th anniversary of the auction house, a whopping US$7.3 million was paid for a ring mounted with a spectacular 8.388-carat Burmese ruby in modified oval shape, accentuated with diamonds. The ring was crafted by Cartier. Accompanying gemological reports issued by well-established gem labs SSEF and Gübelin in Switzerland indicate that the gemstone has not undergone any heat treatment.
Meanwhile a jadeite and diamond necklace fetched US$6.4 million at the auction. The necklace consists of 43 jadeite beads of evenly intense green colour with high translucency, ranging from 13.59 to 11.42mm in diameter.
