Cullinan Diamond Mine Tour

The Cullinan Diamond Mine Tour takes place in the town of Cullinan, about 45 minutes east of Pretoria in Gauteng province, South Africa, with its base at 1 Oak Avenue. The Premier Mine here is famous as the source of the Cullinan diamond, found in 1905 and weighing 3,106 carats, the largest gem-quality rough diamond ever discovered. It was cut into several stones that form part of the British Crown Jewels. The mine has produced many other notable stones, including blue diamonds, and remains one of the country's historic operations. Surface tours, offered on selected days, usually Tuesday to Sunday, explain the history of the mine and the town. Guides walk visitors through the mine's surface workings and viewing points, including the enormous open pit known as the Big Hole, and show how diamonds were found, processed and valued. Tours also cover the story of the mine's founder Sir Thomas Cullinan, the development of the village and the working lives of miners. Underground tours have been offered at times, but availability depends on current operations and safety rules, so visitors should confirm what is on offer when booking. A typical tour lasts about two hours. Cullinan village is worth exploring, with well-preserved early twentieth-century buildings, cafes, and craft shops along the main street, and jacaranda trees that flower in October. Booking ahead is essential, as tour slots are limited and the mine is an operating site. Visitors should wear closed shoes and expect to follow safety instructions. Photography is generally allowed in permitted areas, though restrictions apply near mine operations. A rental car is the easiest way to arrive, and organised tours from Pretoria and Johannesburg are also available.
