largest diamond found
The biggest of the three diamonds was found using the latest in recovery technology. With older equipment, Lamb said, it might have been missed and been ground up with waste stones. The largest gem quality diamond was the 3,106 carat Cullinan Diamond found in South Africa in 1905. From that was cut the First Star of Africa which now adorns the Royal Scepter -- one of the British crown jewels now on display at the Tower of London.
