HONG KONG.- Tiancheng International Jewellery and Jadeite Autumn Auction 2016 concluded with triumph today, realising over HK$100 million/US$13 million, with nearly 60% of total value sold and 63% of lot sold. It is noteworthy that all white jade ornaments and jewels were sold and nearly 20% of all auction items were sold above estimate. Together with the spring auction, Tiancheng achieved HK$228 million/US$29 million in 2016, and four auction records were also set in the spring charity auction. 

The top lot of the auction belongs to the 42.42-Carat Natural Unheated Burmese Mogok "Cornflower Blue" Sapphire Necklace by Cartier. Bidding opened at HK$12 million, followed by an intense battle among room bidders and phone bidders. Abruptly another phone bidder jumped in at HK$16.5 million and after a total of 12 bids, the magnificent piece was hammered at HK$17 million, which was eventually sold for HK$ 20.4 million/US$ 2.6 million including the buyer’s premium. This diamond necklace was crafted with a marvellous 42.42-carat sapphire of superb quality by French jeweller Cartier in the 1950s. Created at a challenging time when the world was barely recovering from the devastation of the Second World War, this necklace is a treasure of extreme rarity. It is the epitome of Cartier’s highly selective use of gemstones in the 1950s: the sapphire glows with an intriguing saturated colour and impressive clarity that sets it apart from most stones of its kind, and is accompanied by a pear-shaped D-colour Type IIa diamond weighing over 11 carats. The diamond necklace weighing approximately 27.50 carats is meticulously crafted with a delightful design that evokes the curves of a ribbon flowing gracefully towards the sapphire and diamond pendant
