Lesedi la Rona: The World’s Largest Uncut Diamond

The Lesedi la Rona is a precious stone found in Botswana in November 2015.

The diamond which was exhibited at the Sotheby’s auction in London failed to sell.

The base ball-sized diamond is the largest ever to be found. This is equally the first time an uncut diamond of that size will be publicly auctioned.

Lesedi la Rona which is believed to have existed for over 2 billion years is 1,109 carats. The diamond took its name from Botswana’s Tswana language which means “our light”.

It was discovered by Lucara Diamond Corp’s Karowe mine, a Southern African based Canadian mining company.

All things being equal it, was expected that the precious stone from African soil will sell for more than £52 million ($70 million). Unfortunately the available bid was not up to it. The highest bid was about £45 million ($61 million).

The Sotheby auction house recognized the Lesedi la Rona diamond as “the find of a lifetime”. Perhaps it has proven that it is indeed priceless as no bidder could afford the African treasure. Lesedi la Rona is still in the possession of Lucara Diamond.

In terms of size, Lesedi la Rona is only smaller to the Cullinan Diamond, mined in South Africa in 1905.

The Gemological Institute of America, certifies that the colour and transparency of the diamond indicates that it is a type IIA diamond. This means that this uncut diamond found in Africa is “the most chemically pure” type.

The firsts of the type IIA diamonds were discovered in Golconda, India. They are usually the Cullinan I and the Koh-i-Noor. These type of diamonds can be found in the British Crown Jewels. The Queen’s jewel contains 9 stones cut from a 3,106-carat diamond.

In March, a massive 404.2 carat diamond was discovered in Angola by an Australian mining company. It was estimated to a $14 – $20 million worth. It was recorded as the 27th largest in the world.
