PINK DIAMOND COULD FETCH $50M AT CHRISTIE’S AUCTION
Christie’s next week will put under the hammer the largest fancy vivid pink diamond the famed auction house has ever sold and expects to fetch $30 million to $50 million for the nearly 19-carat, rectangular-cut gemstone. The “Pink Legacy” will be put up at Christie’s fall jewelry auction in Geneva on Tuesday. It once belonged to the Oppenheimer diamond family, and Christie’s says it qualifies as a Type IIa diamond – the most chemically pure stones with little, if any, nitrogen. On Wednesday, Sotheby’s will auction jewelry once owned by French Queen Marie Antoinette that hasn’t been seen in public for 200 years.
