Auction of the Lesedi La Rona on June 29


Discovered by Lucara Diamond Corp. at their Karowe mine in Botswana in November 2015, the 1,109 carat Lesedi La Rona, meaning “Our Light” in Botswana’s Tswana language, is the largest gem-quality rough diamond to have been discovered in over a century, and the largest gem-quality diamond in existence today.

First formed between 2.5 to 3 billion years ago, the diamond is roughly the size of a tennis ball and is of exceptional transparency and quality according to the Gemmological Institute of America. Sotheby’s has been given the honour of offering Lesedi La Rona at auction in a standalone sale in London on 29th June. Lesedi La Rona will be on view in London from 18–20 and 25–28 June.

The magnificent stone, which originated from the south lobe of Lucara’s Karowe Mine, is the world’s second largest gem quality diamond ever recovered and the largest ever is a gem quality, Type IIa diamond. The stone measures 65mm x 56mm x 40 mm in sizes and is the largest ever to be recovered in Botswana. 

Lesedi La Rona is roughly the size of a tennis ball; this historic stone would make any other gem look diminutive. it has already been identified by the Gemological Institute of America as possessing exceptional quality and transparency, it might make other precious stones look a bit dull. This will be offered at a stand-alone sale, and that Sotheby’s jewellery division chairman David Bennett would call it “the find of a lifetime.” He adds, “No rough even remotely of this scale has ever been offered before at public auction.
