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

We were very disappointed by the Culling underground tour for the following reasons: 1. The website should have made a mention that you will not be wearing your own shoes. It specifically states 'wear comfortable shoes as there is a fair amount of walking involved' which all in our party did (4 of us) and we all ended up wearing bad fitting gum boots, some us two sizes too large as our sizes were not available. It made the tour extremely uncomfortable given the amount of walking, in semi lit areas on uneven surfaces. For my 70 year old mother in law the tour at times became quite precarious because of the poor fitting boots. 2. You see nothing of the mining when you're underground; you walk for ages through a dimly lit tunnel and see nothing except the walls of the tunnel and an emergency hide away room which looks like it should have been taken our of use about 20 years ago. Not sure why we had to walk such a distance to then trek all the way back again (in our bad fitting gum boots!!!). The highlight was when a train full of rubble came by and tipped it into a hole, resulting in copious amounts of dust clogging the atmosphere. Could have done without seeing (inhaling) that.... Also a mention of the dusty conditions should be made on line in case there are astma sufferers thinking of booking the tour!!! 3. The website makes no mention that you are not allowed to take your phones underground for security reasons. We fully understand this is a rule for safety reasons, but it should clearly be mentioned upfront so one can take a camera with instead. Most people use their phones to take pictures these days - as is the case for us - as we weren't allowed to take these with we didn't take a single picture underground. Very disappointing! 4. At the end of the tour we're led through a serious of shops/restaurant. There was not mention of this upfront and as we had to leave our bags behind no one had any money with them to buy anything, again badly managed. 5. The fact that you have to clean your own boots at the end of the tour is ridiculous. I've paid 600 rand for a tour on which I see very little, have to walk a great distance in badly fitted boots and at the end I have to clean the dirt off them with a brush.... not impressed. 6. Finally; a lot more could be made of this tour by showing guests the different steps of the process: the sorting of rocks, a section underground where something actually happens and not just a long walk through an empty tunnel, etc. If this is not possible due to security concerns then the tour should be substantially shortened and reduced in price as all one is getting for their money is a hot, uncomfortable walk and a long elevator ride. We will not be recommending this tour to others. - David Somers

We had a lovely greeting by Grace, only to find out that my wife and I were the only people on the below ground tour. Toy was our guide and full of knowledge regarding the mine and its operations. We arrived at 10am and left at 4pm what a full day. - Graham Yates

Very interesting tour of the mine Tour guide worked here for decades and explained very well. He was proud to show the organisation and layout of the facilities. We had utmost interest in listening him Visiting an active mine really is a plus - Francois Leblond

The guide didn't give much information about the history of the mine or the mining activity today. What a pitty! - Marie Paternault

It was a great moment to descent to -763 meters, to walk along the tunnels, and to meet miners. Special thanks to Lee for his explanations and his kindness (and for the photos, sent by mail). - Jean DE DAVE
