Weight: 3106ct rough
Origin: Transvaal, South Africa
The Cullinan, the largest gem quality diamond ever found, was discovered at the Premier Mine on 26th January 1905. The rough diamond was nearly flawless and named the Cullinan in honour of Sir Thomas Cullinan, the founder of the Premier Mine, who was visiting that very day. Louis Botha, premier of the Transvaal, persuaded his government to buy the diamond for approx. US $1 million and presented it to England’s King Edward VII as a token of thanks for granting Transvaal its own constitution.
The Cullinan was handed to Amsterdam’s House of Asscher to polish. The diamond was divided into 9 major gemstones, 96 smaller stones and about 19.5cts of unpolished pieces. The two largest gems were kept for England’s regalia and the rest went to Asscher as payment. King Edward bought one of the major gems for his consort, Queen Alexandra. The Transvaal government bought the remaining stones and pieces, and presented the other 6 major gems to Queen Mary in 1910. Two of the small stones were presented to Louis Botha, who gave one to his daughter when she turned 17.
