London - Sotheby’s unveiled an 11-carat fancy vivid pink diamond expected to sell for upwards of $20 million in a single-lot auction in October. Dubbed the “Williamson Pink Star,” the diamond is the product of a 32-carat rough stone unearthed at the Williamson mine in Mwadui, Tanzania, the country’s only major diamond mine that is known for its “bubble-gum pink” stones. Diacore bought the diamond for $13.8 million, or about $427,000 per carat, from mine operator Petra Diamonds in December 2021. At the time, Diacore Chairman Nir Livnat described it as a “rare masterpiece of nature.” The company, which has cut a number of high-profile blue diamonds including the “CTF Pink Star” and the “De Beers Cullinan Blue Diamond,” was able to craft the 32.32-carat chunk of rough into a 11.15-carat internally flawless cushion-cut diamond that is graded fancy vivid pink. Sotheby’s said it is the second largest IF fancy vivid pink diamond ever to appear to auction. The largest is the 59.60-carat CTF Pink Star, so named by its purchaser, Chow Tai Fook. The Chinese jewelry giant paid $71.2 million for the diamond in April 2017, and it remains the most expensive diamond, colored gemstone or jewel ever sold at auction.
