Once a rough diamond has formed 150-200 kilometres below the earth’s crust it will be transported to the surface through kimberlite pipes – named after the South African town, Kimberley where the pipes were first discovered. … Once the diamonds are mined they will then be sold to the manufacturers.
How are diamonds transported from mines?
Once this ore is broken, it is loaded and then transported to a primary ore crusher where the diamond extractor process begins. Miners tunnel through the Earth’s crust to reach the kimberlite pipe. … Here, loaders collect the broken ore and bring back to the surface for processing.
How are diamonds transported in South Africa?
Today specialised ships mine for diamonds deep out to sea. These ships use a powerful crawler that sucks up gravel on the seabed through flexible pipes. Sometimes a large-scale drill mounted to a ship is used to excavate for diamonds.

Why does Africa have so many diamonds?
Diamonds in Africa were formed somewhere between 600 million and 3 billion years ago when titanic-force pressure and heat caused carbon 1,200 miles (1,931 km) below the Earth’s surface to crystallize. As recently as a million years ago, erupting molten rock brought the diamonds closer to the Earth’s surface.
