GENEVA, May 12, 2010 – A blue, cushion-shaped diamond weighing 7.64 carats sold on May 11 at Sotheby’s magnificent and noble jewellery sale for a whopping 8.93 million Swiss francs ($8 million) to an anonymous buyer who paid double the pre-sale estimate.
A rare “Toi et Moi” ring by Alexandre Reza featuring a 5.02-carat fancy vivid blue diamond, which sold for 7 million Swiss francs ($6.3 million), was an auction record for a jewel by the French jewellery maker. Sotheby’s pre-sale estimate was $4 million to $7 million.
A white emerald-cut diamond weighing 52.82 carats fetched 8.8 million francs ($7.9 million).
Several pieces belonging to Brazilian socialite Lily Marinho found new owners, including an emerald and diamond necklace and matching ear clips and ring which achieved 1.2 million francs, tripling the pre-sale estimate.
