The Cullinan diamond, world’s largest gem diamond, which weighed about 3,106 carats in rough form when found in 1905 at the Premier mine in Transvaal, South Africa.

This is the largest diamond. The Golden Jubilee is still not as large as the Excelsior diamond which was 970 ct. uncut.

If you want to talk about an expensive ring, look no further than this 10.8 million dollar beauty. It’s the world largest diamond which was sold at Christie in Hong Kong. It’s five carats of pink diamonds surrounded by white diamonds.
