Billionaire Buys World’s Most Expensive Diamond

Blue Diamond

An Asian billionaire has purchased the world’s most expensive diamond. The vivid blue stunner weighs in at a hefty 12.03 carats.

The ‘Blue Moon’ diamond was sold for a whopping $48.4 million, making it the world’s most expensive diamond.

According to the auctioneer David Bennett, it is the “highest price per carat” ever obtained for any kind of stone.

The diamond was purchased at a Sotheby’s auction in Geneva. The successful bidder renamed it, ‘Blue Moon of Josephine.’

One day earlier an anonymous bidder in Geneva purchased a 16.08-carat pink diamond for $28.5 million. He named it ‘Sweet Josephine.’

CNN confirmed after the auction that billionaire Joseph Lau, of property firm Chinese Estates Holdings, purchased the diamond.

“Yes, the diamonds were bought by Mr. Joseph Lau for his daughter,” his assistant told CNN.

This isn’t the first time he has purchased large gems for his 7-year-old Josephine. He also buys jewels for 13-year-old Zoe.

The ‘Star of Josephine” is named after a 7.03-carat blue diamond that was purchased in 2009 for $9.48 million.

The 9.75-carat blue diamond purchased for $32.6 million was named ‘The Zoe Diamond’ and a Burmese ruby and diamond brooch weighing 10.10 carats sold for $8.43 million, and was quick renamed ‘The Zoe Red.’

Lau is a prominent collector of art, diamonds, wine, and various other uber expensive collectibles.
