The Cullinan I and II

The colourless pear shaped stone with a weight of more than 530 carats ( 106 g ) , called « The Great Star of Africa » by Edward the VII, is one of the biggest diamonds in the world.
For many years, it had been the largest polished diamond in the world until the 1985 discovery of the Golden Jubilee Diamond, which weights 545.67 carats (109.13 g).
Cullinan I still remains the largest colourless diamond in the world though: the Golden Jubilee one has a yellow-brown colour. Incidentally, both diamonds were discovered at the same mine – the Premier Mine in South Africa.

It is set in the British Royal Scepter, which was specially reconstructed to inhabit the stone in the design.
The scepter is on permanent exhibition in The Tower of London.
