At over 18 carats, the vividly coloured gem is the largest pear-shaped pink diamond of its quality ever to be offered for sale at auction, the Christie's auction house said.
In 2018, Christie's sold the 18.96-carat Winston Pink Legacy, which raked in over $50 million -- the highest per-carat price ever paid for a stone of its kind. The giant Raj Pink diamond, weighing a full 37.3 carats, meanwhile, failed to sell at a Sotheby's auction a year earlier, where it had been estimated at up to $30 million.
