De Beers Exceptional Blue Collection Goes on Sale at Sotheby’s

The De Beers Exceptional Blue Collection, comprising eight blue diamonds recovered from Petra’s historic Cullinan mine in South Africa – are to go on sale in Geneva, New York and Hong Kong from November 2022 to early 2023, IDEX Online reports. If each diamond is sold at its highest estimate, the collection could end up raking in $85 million.

 

The De Beers Exceptional Blue Collection has a total of just over 32 carats, and its most impressive diamond is the De Beers Exceptional Blue – a 11.29, a step-cut Fancy Vivid blue weighing 11.29 carats that could go for anywhere between $28 million to $50 million. Four of the eight diamonds are graded Fancy Vivid by the GIA, the highest of all color gradings. A 3.24-carat gem, dubbed the De Beers Exceptional, is also graded as “internally flawless.”

 

The collection has been cut from five rough diamonds weighing a total of 85.62 carats jointly bought by De Beers and Diacore in November 2020.
