The 26th of January, 1905 at the Premier mine near Pretoria, South Africa, the largest gem-quality diamond was discovered, the Cullinan Diamond (the Great Star of Africa). The Cullinan was cut into 7 main stones and 96 smaller stones. Edward VII owned the Cullinan I and Cullinan and the remainder of the seven larger stones and the 96 smaller stones continued in the possession of the Dutch diamond cutting establishment, until the South African Government bought these stones and the High Commissioner of the Union of South Africa presented them to Queen Mary.

The largest of the Cullinan diamonds is the Cullinan I. This diamond is pear shaped and 530.2 carat. Another term for the diamond is the Great Star of Africa.
