Cullinan Diamond Mine


Situated about 30 kilometres east of Pretoria, this is one of the richest diamond mines in the world, yielding an average of 2 million carats a year. Cullinan Diamond Mine is a carrot-shaped volcanic pipe and has a surface area of 42 hectares – about 40 soccer pitches

Three of the world’s most famous diamonds the Cullinan, the Centenary Diamond and Premier Rose were mined at the Cullinan Mine. The Cullinan Diamond 3106 ct was given to King Edward the VII on his 66th birthday from England.  


On 26 January 1905 miner Frederick Wells extracted a large diamond from the Cullinan mine, a few kilometres outside Pretoria in South Africa’s mineral-rich Gauteng province. The Cullinan Diamond was the largest gem-quality rough diamond ever found, weighing 3,106.75 carats (621.35 g), discovered at the Premier No.2 mine in Cullinan, South Africa, on 26 January 1905. It was named after Thomas Cullinan, the mine’s chairman. In April 1905, it was put on sale in London, but despite considerable interest, it was still unsold after two years. In 1907, the Transvaal Colony government bought the Cullinan and then presented it to Edward VII, King of the United Kingdom, who had it cut by Asscher Brothers in Amsterdam.

Presentation to Edward VII

Transvaal Prime Minister, Louis Botha, suggested buying the diamond for Edward VII as “a token of the loyalty and attachment of the people of the Transvaal to His Majesty’s throne and person”. In August 1907, a vote was held in Parliament on the Cullinan’s fate, and a motion authorizing the purchase was carried by 42 votes in favour to 19 against. Initially, Henry Campbell-Bannerman, then British Prime Minister, advised the king to decline the offer, but he later decided to let Edward VII choose whether or not to accept the gift. Eventually, he was persuaded by Winston Churchill, then Colonial Under-Secretary. For his trouble, Churchill was sent a replica, which he enjoyed showing off to guests on a silver plate. The Transvaal Colony government bought the diamond on 17 October 1907 for £150,000 or about US$750,000 at the time, which adjusted for pound-sterling inflation is equivalent to £15 million in 2016. Due to a 60% tax on mining profits, the Treasury received some of its money back from the Premier Diamond Mining Company.

The diamond was presented to the king at Sandringham House on 9 November 1907 – his sixty-sixth birthday – in the presence of a large party of guests, including the Queen of Norway, the Queen of Spain, the Duke of Westminster and Lord Revelstoke. The king asked his colonial secretary, Lord Elgin, to announce that he accepted the gift “for myself and my successors” and that he would ensure “this great and unique diamond be kept and preserved among the historic jewels which form the heirlooms of the Crown”.

Today, the diamond consists of nine large stones and ninety-six smaller stones; two of the largest stones forming part of the Crown
