The complete set of nine stones produced from the Cullinan Diamond
RCIN 2800279
The magnificent Cullinan Diamond – the largest ever found – was discovered near Pretoria in South Africa on 26 January 1905. In its uncut state, it weighed 3,106 metric carats and boasted a size of 10.1 x 6.35 x 5.9 cm. This scale, coupled with its extraordinary blue-white colour and exceptional clarity, made it the most celebrated diamond in the world. It was presented to King Edward VII in 1907 by the Government of the Transvaal, as a symbolic gesture to heal the rift between Britain and South Africa following the Boer War. Over eight months, three men worked for 14 hours a day to cut and polish nine large stones from the original diamond. Today, stones I and II are incorporated into the Crown Jewels, set in the Sovereign's Sceptre and Imperial State Crown respectively.
