De Beers Group and Diacore team up for the purchase of the 39.35-carat blue diamond from the legendary Cullinan Diamond Mine

De Beers Group and Diacore have teamed up again for the purchase of an exceptional 39.34-carat diamond from the legendary Cullinan Diamond Mine for US$40.18 million, split equally between the companies.

This partnership follows a similar one in November 2020, where the two diamond companies purchased five rare blue diamonds from Cullinan that totals 85.62 carats. Cullinan has a historic legacy with exceptional diamonds, having produced several of the world's most famous diamonds including the largest rough diamond ever discovered: the Cullinan Diamond.

"It is a privilege to have the opportunity to work with such a miracle of nature and a delight to see the legendary Cullinan deposit producing yet another breathtakingly beautiful gemstone. It’s great to be working again with Diacore on this diamond, given their outstanding history of releasing the true beauty of exceptional finds such as this," says Paul Rowley, executive vice president of diamond trading at De Beers Group.

Meanwhile, executive chairman of Diacore Nir Livnat says, "We’re excited and humbled to have the opportunity of designing and shaping one of the most special and rare blue diamonds of such size and colour. Joining forces with De Beers specialists alongside our master cutters will enable us to create a world-class masterpiece."

De Beers and Diacore will appoint expert artisans to study and work with the rare gemstone so that its beauty can be maximised before it's presented to the world. Blue diamonds are considered much rarer than other fancy colour diamonds—making this 40-carat discovery almost unheard of.
