Mining diamonds in this way requires parallel excavation of two tunnels in kimberlite hundreds of meters underground. These two tunnels may be more than 2000 meters deep, and a horizontal tunnel will be dug from the tunnel to Kimberlite. Then, the ore and the drill blank are transported together. This is a very expensive, complicated and dangerous diamond mining method, which can only be considered after other diamond mining methods are fully used. The advantage of this method is that the mine can play its full potential.

2) Open pit mining:

This is the most commonly used method of diamond mining. This method is only applicable when cracks in the earth's crust allow kimberlite to emerge from the surface or protrude. In order to mine diamonds in prominent mines, a spacious and uncovered area is needed. Then, minerals and dust can be collected and classified. Today, many ores are mined in this way.

3) Alluvial mining:

This is the oldest method of diamond mining. There are one or two main ways to collect diamonds. In this way, diggers need to sort the dust with colander and shovel. These jobs are usually carried out by the river or the estuary where the river enters the sea. This method has developed into organized alluvial mining, and heavy machinery has been used to collect sediments-mud and sand-along the river, and then systematically screen them. This method does not need to drill diamond mines.

4) Marine mining:

In this relatively new way, ships carry giant pumps and install them at the estuary where rivers enter the sea. These ships pump out the sand found there, then sift out the sand and water, and then look for diamonds in the remaining rocks. Usually, the diamonds left in this way are of high quality, because they are strong enough to travel long distances to the ocean. This method is still more expensive than "traditional" diamond mining.

Nature has created diamonds, and of course we should mine them in the most reasonable way while maintaining their original state. At present, only about 20% of diamonds mined in the world are gem-grade, and most of the rough stones can only be used for industrial purposes.
