Christie’s gem auction last week was a success with the 63.93 carat diamond going for $4.2 million (apparently to a husband bidding on it for his wife) and the 478 carat sapphire going for $1.5 million to an anonymous phone bidder. However, Sotheby’s failed to auction off the gigantic 103 carat diamond the following day, as no one was willing to go above the minimum $8.5 million price. In other auction news, the catalog for the British Airways Concorde Charity Sale, to be held on December 1, includes instruments such as Ice Detector Heads and Fuel Pressure Indicators. There’s also passenger seats and a captain’s seat. At Air France’s Concorde auction, the nose cone went for $500,000.
