Diamond Debut for De Beers and Sotheby's Collaboration

(IDEX Online) - The sale of the Jwaneng 28.88 diamond later this month marks the start of a collaboration between De Beers and Sotheby's.

Together they aim to "present exceptional diamonds as works of art," although no details on the terms or scope of the agreement have been made public.

The collaboration centers on joint marketing and storytelling, going beyond a standard consignment, in which the miner selects an auction house.

Both companies co-create a branded narrative - "earth to art" - to promote across their channels

The flawless D-color unmounted Jwaneng 28.88 - cut from a 114.83-carat rough recovered at Botswana's Jwaneng mine (Debswana, De Beers' 50-50 government venture) -leads the auction at Sotheby's Magnificent Jewels & Jadeite sale in Hong Kong on 23 April.

It carries an estimate of HKD 17 million to HKD 22 million (USD 2.2 million to USD 2.8 million).

Other De Beers diamonds from Jwaneng will be offered at the same sale, including a solitaire ring and a pair of diamond earrings.
