Williamson Pink Star sets world record highest price per carat for a diamond sold at auction
An extremely rare “fancy vivid pink” diamond has sold for 453m Hong Kong dollars (£52m) – more than double its estimated price – and set a world record for the highest price per carat for a diamond sold at auction.
The 11.15-carat Williamson Pink Star diamond, which is named after another pink diamond given to Queen Elizabeth II as a wedding gift, was sold to an undisclosed buyer at auction by Sotheby’s Hong Kong on Friday.
