'Magical' blue diamond is auctioned for $48m in Geneva Tycoon buys $48m blue diamond at auction for daughter
(about 7 hours later)
A 12.03-carat Blue Moon diamond has been auctioned in Geneva for $48.4m (£31.7m) Sotheby's has said. A 12.03-carat blue diamond has been auctioned at Sotheby's in Geneva for $48.4m (£31.7m) to a Hong Kong tycoon.
The cushion-shaped diamond, mounted on a ring, was bought by a private collector from Hong Kong. Joseph Lau confirmed he bought the ring-mounted, cushion-shaped stone for his daughter, renaming it "Blue Moon of Josephine" after her.
The sale comes a day after rival auction house Christie's sold a rare 16.08-carat pink diamond for $28.5m. He is also confirmed as the buyer of a 16.08-carat pink diamond, which Christie's sold for $28.5m on Tuesday.
In 2013 a diamond known as the Pink Star was sold for what is believed to be a record breaking $83m (£52m) - also at a Sotheby's auction in Geneva. Lau, a convicted property billionaire, has a history of buying precious stones for his daughter.
In 2009, he bought another blue diamond for her - the 7.03-carat "Star of Josephine" - paying what was then a record $9.5m.
The pink diamond purchased earlier this week has been renamed "Sweet Josephine", a spokeswoman for Mr Lau told BBC News.
Last year he was sentenced to five years in jail in Macau for corruption, but has avoided prison by not visiting the territory. There is no extradition treaty between Macau and Hong Kong.
