The Cullinan Mine
The Cullinan mine is the only operational diamond mine in the world open to visitors. This South African mine site, also known under the official name of Premier Mine, is situated near to Pretoria and the Kimberley Mine known from the Kimberley-Process. This site is worldwide renown partly thanks to the uncovering of the largest rough diamond ever found, the Cullinan diamond. This 3106.75 carat gemstone was discovered in 1905 and the biggest part (The Great Star of Africa) was incorporated in the British crown jewels, exposed in the Tower of London. Ever since the Cullinan Mine is globally known for its clear investment diamonds.
