Bidding for the stone at Sotheby's in Hong Kong began at $56 million. After only five minutes of bidding, the gemstone was sold for $71.2 million, making it the most expensive gemstone ever sold at auction. The BBC reports that "the record until now was held by the Oppenheimer Blue, which sold for $50m last May."
