Sotheby’s to donate eight Blue De Beers diamonds worth over $70 million

Jewelry collectors will soon have several rare opportunities to add a beautiful blue diamond to their coffers.

Starting this fall, Sotheby’s will auction off eight blue diamonds from luxury jeweler De Beers. The group, called the De Beers Exceptional Blue Collection, comes from the famous Cullinan mine in South Africa and is impressive given that blue is the rarest color to be found in a diamond. What makes these eights significant is that their brilliant hue and even color distribution make them particularly rare. Additionally, four of the eight stones have been graded by the Gemological Institute of America (GIA) as “fancy vivid,” the highest rating for colored diamonds. The eight diamonds vary in shape and size, ranging from an oval-shaped 1.2 carat to a stepped cut of 11.29 carats. Together they weigh over 32 carats. The total collection is valued at over $70 million.

“The magnificent De Beers Exceptional Blue Collection is a testament to De Beers’ unique ability to source the world’s rarest diamonds and the patience and foresight required to assemble a collection that transcends rarity and can only be described as remarkable,” says Bruce Cleaver. , CEO of De Beers Group in a statement.

Three of the diamonds will be offered for auction before the end of 2022, while the remaining stones will go under the hammer at later dates. The De Beers Exceptional Blue 5.53, worth $11-15 million, will be sold at Sotheby’s Magnificent and Nobles Jewels auction in Geneva on November 9. The Exceptional Blue 3.24 ($5-8 million) and Exceptional Blue 2.08 ($1.2-1.5 million) will go under the hammer at the Magnificent Jewels auction in New York on December 7 .

This is not the first time that Sotheby’s has offered geological rarities. In fact, in April, the house auctioned off a 15.10-carat De Beers blue diamond for $57.5 million.

“The market for colored diamonds and gemstones has never been stronger, so we are absolutely delighted to offer the first diamond from this superb collection,” says Olivier Wagner, Head of Sotheby’s Magnificent Jewelery Auctions at Geneva, in a statement.
