When the Pink Star was last brought to auction by Sotheby's in 2013, it almost became the world's most expensive diamond. However, the winning bidder Isaac Wolf was unable to pay the $83 m promised and Sotheby's was forced to retain the diamond. The sale on 4 April marks a new chapter in the story of this extraordinary diamond. The buyer is Hong Kong jewellery retailer Chow Tai Fook Jewellery.
