Last Wednesday a flawless Blue Moon Diamond sold for $48.4 million to a Hong Kong billionaire, setting a world record at the Sotheby’s auction. After buying the 12.03-carat “Blue Moon” diamond the Chinese billionaire Joseph Lau said that he had bought the ring for her 7 year old daughter and called it the “Blue Moon of Josephine”. The Guardian reported that, David Bennett, the head of Sotheby’s international jewellery division, said the “Blue Moon” sale broke several records and made the gemstone the most expensive diamond, regardless of colour, and the most expensive jewel ever sold at auction. It also fetched the highest-ever price per carat, he said.
