British jewelry company, Graff, says that it has purchased the world's largest uncut diamond for $53 million.
The 1,100-carat gem is called the Lesedi La Rona diamond, and it’s roughly the size of a tennis ball. Canadian miner, Lucara Diamond, says it found the diamond in Botswana in late 2015. It could be cut into smaller gems or left whole in a private collection.
Graff is already the owner of a 373-carat diamond, which was bought earlier this year and formed part of the original stone.
