Exceptional Pink Diamond Could Fetch Over $21 Million At Auction

An exceptional pink diamond, called "Williamson Pink Star", considered one of the world’s purest, could sell for more than $21 million at an October auction organized by Sotheby's in Hong Kong.

According to Sotheby's, Williamson Pink Star is the second largest internally flawless, vivid pink diamond ever appearing at auction.

The dazzling pink diamond is outsized only by the record-breaking CTF Pink Star, the 59.60-carat oval mixed-cut diamond, which sold for $71.2 million US in April 2017 also at an auction organized by Sotheby's.

Such Pink Diamonds Are Exceptionally Rare

"Such is the perfection and purity of the Williamson Pink Star that, with an estimate of $21 million US / $170 million HK, it has the potential to set a new per-carat price record for a Fancy Vivid pink diamond at Sotheby’s Hong Kong this October, leading the 2022 Hong KongAutumn Sales.

A natural wonder of nature, the extraordinary cushion-shaped stone has been named in homage to two legendary pink diamonds: first, the CTF Pink Star, noted above; and second; the celebrated ‘Williamson' stone – a brilliant-cut diamond of 23.60-carats given as a wedding present to Her Majesty Queen Elizabeth II in 1947 by the Canadian geologist and royalist, Dr. John Thorburn Williamson, who owned the Williamson mine in Mwadui, Tanzania, where it was discovered," Sotheby says.

Ahead of the auction, the "Williamson Pink Star" will go on tour to Dubai, Singapore, and Taipei before arriving in Hong Kong where it could fetch more than $21 million when it goes under the hammer.

"(Pink diamonds) are exceptionally rare in nature...," Kristian Spofforth, Sotheby's head of jewelry, told Reuters at a press preview.

"You then add in the extra factors like it being over 10 carats, internally flawless, and Type IIA, and you get right down to the pinnacle," he added referring to a subgroup of the most chemically pure diamonds", he added.
