1,109 carat Lesedi La Rona diamond was recovered from a Botswana mine by Canada’s Lucara nearly two years ago. This makes the diamond worth $47,777 (£35,374) per carat.
Its name means ‘our light’ in the Twsana language which is spoken in Botswana.
The Lesedi La Rona went unsold at a Sotheby’s auction last year where it was expected to fetch $86m (£63m).
The diamond, which is roughly the size of a tennis ball, is second in size to the Cullinan, which was discovered in South Africa in 1905 and is the largest diamond in the world.
