Cullinan Underground Mine Tour


Activity Description

The Cullinan Diamond Mine is renowned as a source of large, high-quality gem diamonds, including Type II stones, as well as being the world’s most important source of very rare blue diamonds.

Cullinan earned its place in history with the discovery of the Cullinan diamond in 1905, the largest rough gem diamond ever found at 3,106 carats, which was cut to form the two most important diamonds in the British Crown Jewels. Many of the world’s most famous diamonds herald from Cullinan, and it continues to produce world-class diamonds under Petra’s stewardship.

The Cullinan orebody contains a major diamond resource of 195 Mcts, suggesting a potentially long life for the operation of +50 years.
Come and enjoy with us exclusive surface and underground tours of the working Cullinan Diamond Mine.

This mine has produced some of the world’s largest high quality gemstones and is the home of the world’s largest diamond – the Cullinan (3106 ct).

Recently, a number of record braking blue diamonds have been found including a 122.52 carat diamond which achieved a value of US$ 27.6 million in 2014.

After visiting the mine, you will get the opportunity to visit the Cullinan Diamond Mine market for an unforgettable diamond and jewelry shopping experience.

Customer Reviews

I must say that It was a thrilling experience but at the same time disappointing because of the lack of information given about the mine overall. We asked lots of questions and we were given answers but still it shouldn't be like that all the way. The underground visit is superb but it should also include some overground tours because that's where you really get to see what's coming from down under. Thank you Max - Massimiliano Duca

I greatly enjoyed the underground tour. Our guide went to great lengths to explain and show everything he could, the tour was excellently organized and on time. I loved being in a new for me place: 763 mètres or thereabouts, straight down. Also, North Americans would never have the freedom to explore a Real working mine during work operations, and I greatly appreciate that freedom. Cullinan is lovely for lunch, too. - frankie alessio

Service was great, staff friendly and tour very interesting. Uncle George deserves a (diamond) medal!!!!!!!!! - Evert deVries

Great guide (Toy)!!! The whole clothing and scribing in procedure took much to long. This part could be much better organised. But we enjoyed the tour, no regrets! - Dorothee Bunge

For the underground tour please make note that no cell phones are allowed at all. So bring a camera. You have to get completely changed into overalls and boots. This takes a long time especially in a big group. It is advisable to remove all clothing and just wear the overall as it gets very hot underground. George our guide was excellent. Very interesting. - Jane Wilks
