Thursday, 6 April 2017 : The Pink Star diamond is one of the world’s largest and most flawless diamonds to ever go to auction, and it sure brought in a pretty penny.
Sotheby’s sold the rare 59.6-carat piece Tuesday at an auction in Hong Kong for $71.2 million to a jewelry retailer Cho Tai Fook.
The Pink Star is an internally flawless fancy vivid pink diamond that was mined in South Africa by De Beers in 1999. Cutting and polishing the diamond was a process that took two years, and then later graded by the Gemological Institute of America. GIA is a public non-profit institute that researches gems and sets quality standards.
“This is the largest fancy vivid pink they’ve ever graded, so I think we’re looking at the biggest, pinkest diamond known,” said David Bennet, Sotheby’s worldwide chairman for international jewelry, in an interview for SothebysTV.
Most everyone knows the 4 Cs of diamond quality — color, cut, clarity, and carat. Pink diamonds are pretty rare and ones with strong color are even rarer, according to John King, GIA’s chief quality officer.
There’s no doubt that the Pink Star has a unique beauty, and an impressive size, but that doesn’t mean the jewel was easy to sell, according to the Los Angeles Times.
In 2014, Sotheby’s put the Pink Star up for auction in Geneva where it sold for $83.2 million to diamond dealer Issac Wolf. When Wolf’s investors backed out, the dealer was forced to default and left the rare gem without a home. Sotheby’s attempted to get the Pink Star sold in private sales for three years without success.
It was decided that the diamond would go back to auction this year, this time in Hong Kong to take advantage of a growing Asian jewelry market.
The move proved to be wise, as the April 4 sale shattered the record for a diamond sold at auction by over $13 million. In 2016, the Oppenheimer Blue diamond set the record for a diamond successfully sold at auction with a $57.5 million sale in Geneva.
