How Diamonds Are Mined

We barely think about the way in which the diamonds we wear came to us. Natural diamonds, versus man-made diamonds or fake diamonds, are mined from the earth. There are presently 2 systems of mining diamonds : Pipe Mining and Alluvial Mining.

When pipe mining is utilized, the diamonds are removed from the earth thru volcanic pipes. These aren't synthetic pipes. These are natural pipes in the ground. Shanks are put into the ground next to the pipes, and tunnels are driven into the deepest parts of the pipe. The diamonds aren't fixed at the mine. Instead, big rocks that are full of diamonds are brought out of the mine and moved to a screening plant for separation. The Alluvial mining methodology is done in riverbeds and on beaches. Walls are built to restrain the water and the sand on the bank or beach is moved with a bulldozer till the level of earth that diamonds can be discovered in is reached. Again, the diamonds aren't sorted here.

Instead, the sand that contains the diamonds is bulldozed into wagons, and taken to screening plants.
