The world's rarest diamonds available to buy

2 of 15 2/15
The Lesedi La Rona rough diamond

Lesedi La Rona rough diamond

At a huge 1,109 carats, the tennis-ball sized Lesedi La Rona rough diamond was first honoured with its very own auction at Sotheby's London on June 29, 2016 but, after failing to reach its minimum, has recently been acquired by British fine jewellery house Graff in a deal valued at $53 million. Discovered in November 2015 in the Karowe mine in Botswana, it has already been certified as possessing qualities "commonly associated with Type IIa diamonds" by the Gemological Institute of America and is being hailed as the most momentous discovery since the 3,106 carat Cullinan Diamond was unearthed in 1905.

Although not as large as the Cullinan, the Lesedi La Rona's composition means it has the potential to yield the world's largest top-quality diamond once it has been cut and polished. Now in the hands of one of the world's finest diamond experts, time will tell what Graff's master craftsman are able to create from this stunning stone and what treasures await potential buyers.
