Mr. Lau has already exercised his right to name the diamond, which is now known as ‘Star of Josephine’, Sotheby’s said in a statement.
The exceptional blue diamond, which was extracted by Petra Diamonds from the renowned Cullinan mine in South Africa, set two auction records at Sotheby’s sale — the world record price per carat for any gemstone at auction and the world record price for a fancy vivid blue diamond at auction.
