How Diamonds Are Mined
Diamond Mine Facts



When it comes to diamonds there are a lot of unanswered questions such as: where are diamonds mined? How are diamonds mined? Who can own a Diamond Mine? What are synthetic diamonds? What are colored diamonds and how does a person spot a fake diamond? In this session we’re going help you understand the diamond mining process.


How Diamonds Are Mined

Prior to placing a diamond ring on someone’s finger, that diamond goes through an intensive process. It has to be: mined, processed, shipped, inspected, cut, polished and then set.


Only after those steps are complete is a diamond ready to be sold to the retail market. With all of these numerous steps, it’s no wonder that diamonds are among the world’s most expensive items. To add to the costs, for every diamond mined, far less than half of them will be gem quality. What happens to the rest of the diamonds?


They are placed into two other categories: industrial quality and near-gem quality. In order to receive the stamp of approval as gem quality, a diamond must display the highest standard of excellence. See Brilliant Cut Diamonds.


Trained eyes painstakingly seek out any flaws. But before they can be professionally graded, the diamonds must be mined. Here is a list of all of the diamond mines throughout the world.

How Diamonds Are Mined - The Diamond Mining Process
Naturally genuine diamonds are mined from the earth. There are currently two methods of mining diamonds: Alluvial Mining and Pipe Mining. The Alluvial mining method is done on beaches and in riverbeds.


Walls are built to hold back the water and then the sand on the beach or bank is moved with a bulldozer until the level of earth that diamonds can be found in is reached. The diamonds are not sorted here; instead, the diamond rich sand that contains the stones is hauled off into trucks and taken to screening plants to be processed.


With pipe mining, diamonds are extracted from the earth through natural pipes in the ground called volcanic pipes. Shanks are put into the ground next to the pipes, and tunnels are driven into the deepest parts of the pipe.


The diamonds are not sorted out at the mine. Instead, huge rocks that are full of diamonds are brought out of the mine and moved to a screening plant for separation. And that’s the diamond mining process in a nutshell.
