Williamson "Pink Star" Sets World Record For Highest Price per Carat

Selling to an undisclosed buyer at the Sotheby’s auction house in Hong Kong, the Williamson Pink Star diamond sold at 58 million dollars, fetching more than double the anticipated sales price. The pastel-hued diamond was named in honor of two other pink diamonds, the CTF Pink Star, which sold for $71.2 million in 2017, and the "Williamson" diamond, a pink diamond gifted to Queen Elizabeth II.
The pink colored 11.15-carat diamond is a rare find among gem quality stones and was discovered at the well-known Mwadui mines in Tanzania.
It has already been a good year for diamonds on auction. Many of these unique pieces go above and beyond expectations.

In 2021 Antwerp welcomed a rare 39.34 carat Type IIb blue diamond recovered at Petra Diamonds' Cullinan mine, sold for $40 million. The De Beers Blue, the largest vivid blue diamond ever to appear at auction, fetched more than $57.4 million and approximately $3.8 million per carat, making it at that moment one of the highest prices ever achieved for a diamond at auction.
With 5,2 million dollars per carat, The Williamson Pink Star can crown itself as the newest price breaker.
