World's biggest diamond discovered

A gem stone which could become the largest polished round diamond in history has been discovered in southern Africa.

The massive stone weighs 478 carats and was found in gem mines in Lesotho, which have already produced three of the world's biggest diamonds over the years.

Another similar sized rough stone from the same mine was recently valued at 12 million US dollars, but the clarity and round shape of this gem mean it could be worth considerably more.
