The “De Beers Millennium 4” diamond is set to be auctioned by Sotheby’s Magnificent Jewels and Jadeite Spring Sale in Hong Kong on April 5. This “rare and superb” diamond is a 10.10ct oval, fancy vivid blue diamond and is estimated to be worth $30 – $35 million.
The diamond was unveiled by De Beers in 2000 as one of 12 diamonds in their “Millennium Collection”. The diamonds, which were all on display at London’s Millennium Dome, were the target of an audacious armed gang who attempted to steal the diamonds using a JCB and sledgehammers. The attempted theft was foiled by police who had replaced the genuine gems with fake stones, thwarting what could have been the biggest diamond heist in modern history.
The internally flawless oval diamond is the largest overall fancy vivid blue to appear on auction, and is being sold by it’s current owner, an Asian collector. The stone will be displayed at Sotheby’s Singapore, New York, London, Geneva and Taipei offices ahead of it’s Hong Kong auction.
Quek Chin Yeow, Sotheby’s deputy chairman for Asia and chairman of international jewelry for the continent. “This beautiful blue stone combining nature’s rare beauty, superlative colour, unusual shape and illustrious provenance offers yet another wonderful collecting opportunity for connoisseurs worldwide.”
