WORLD'S LARGEST DIAMOND

A huge gem stone which could become the largest polished round diamond in history has been discovered.
The massive stone is the 20th largest rough diamond ever found, weighs 478 carats and is said to be of outstanding clarity.
It was recovered earlier this week at the Letseng Mine, in Lesotho, a small kingdom in South Africa.
Another similar sized rough stone from the same mine was recently valued at $12million.
But the clarity and round shape of the new gem mean it could be worth considerably more and in its polished state could fetch tens of millions of pounds.
