Pink diamond expected to fetch more than £20m at Hong Kong auction

The second largest, internally flawless “fancy vivid pink” diamond ever to appear at auction is expected to sell for more than £20m when it goes under the hammer at Sotheby’s in Hong Kong on Friday.

The 11.15-carat, cushion-shaped diamond, known as the Williamson Pink Star, is named after two other huge pink diamonds: the 59.60-carat, mixed-cut, oval Pink Star diamond that sold for a record $71.2m at auction in 2017, and the Williamson stone, a 23.60-carat diamond given to the late Queen Elizabeth II as a wedding gift by the Canadian geologist and ardent royalist John Thorburn Williamson in 1947.

Mounted as a floral brooch designed by Frederick Mew of Cartier in 1953, the Williamson is said to have been a favourite of the Queen who wore it on many occasions during her reign, including the silver jubilee.

Williamson owned the Mwadui mine in Tanzania where the Williamson stone and the Pink Star were discovered.
