World's Largest Diamond Is up for Sale

The largest square-emerald cut diamond in the world is up for sale, Graff Diamonds announced on Wednesday. The 302-carat diamond, called Graff Lesedi La Rona, is the principal diamond from the 1,109 carat Lesedi La Rona rough diamond found in 2015 in Botswana. Given the diamond's large size, a new scanner had to be especially made so that gemmologists would be able to analyze and cut it.
