Star of Josephine 7.03 carats fancy vivid blue, internally flawless

Mr. Joseph Lau Luen-Hung names Cullinan blue diamond ‘Star of Josephine’
19 May 2009
Petra Diamonds announces that the important fancy vivid blue, internally flawless, cushion-shaped diamond weighing 7.03 carats, which sold at auction by Sotheby’s last week, was acquired by Mr. Joseph Lau Luen-Hung, renowned Hong Kong collector and connoisseur. Mr Lau bought the diamond for HK$74 million (US$9.48 million) and he has already exercised his right to name the diamond, which is now known as ‘Star of Josephine’.
The exceptional blue diamond set two auction records at Sotheby’s Geneva on 12 May - the world record price per carat for any gemstone at auction and world record price for a fancy vivid blue diamond at auction.
The blue diamond ranks among the most important diamonds ever to be offered for sale by Sotheby’s. It was cut from a 26.58 carat rough discovered in 2008 at Petra Diamonds’ historic Cullinan diamond mine in South Africa, the world’s most consistently reliable source of blue diamonds.
