A dazzling pink diamond named the Williamson Pink Star has sold for £52 million at an auction in Hong Kong – more than double its estimated value.
At 11.15 carats, the Williamson Pink Star is the second largest internally flawless fancy vivid pink diamond to ever appear at auction.
Fine jewellery and engagement ring specialists at Steven Stone have revealed everything you need to know about the vivid pink sparkler – including the royal connection that is likely to have helped elevate its value.
The name “Williamson Pink Star” is a tribute to two other famous pink diamonds – “CFT Pink Star” and the “Williamson” stone.
CFT Pink Star
The CFT Pink Star is a 59.60-carat oval mixed-cut diamond which sold for a record $71.2 million when it went to auction in 2017 – five years on, it still holds the world auction record for any diamond, gemstone or jewel.
Williamson Stone
The Williamson stone is a 23.60 carat diamond that was given to Queen Elizabeth as a wedding gift by Canadian geologist, John Thorburn Williamson. Worn by the monarch in her Williamson brooch, it was discovered in his mine in Tanzania – the same mine in which the Williamson Pink Star was discovered.
As a rough gem, it weighed 54.5 carats, and Princess Elizabeth displayed it at St. James’s Palace ahead her royal wedding to Prince Philip. She later turned to diamond cutters Briefel and Lemer to transform the rough diamond into a faceted gem.
Worth £25,000,000, the Williamson brooch is the second most valuable brooch in the Queen’s collection.
