How Diamonds are Made?

Diamonds is known as the hardest natural substance and is found in a specific type of igneous rock called kimberlite. The diamond is a chain of carbon atoms crystallized and it has a unique hardness as a result of densely concentrated nature of carbon chains.

The most common method used in digging diamonds from kimerblite deposits is black method for it offers the highest yield and cost effective. In the crushing operation, the bigger chunks of kimberlite are cracked into more transportable segments. After the primary crushing, the kimberlite will pass through a grizzly and they are send back for advanced crushing. The crushed kimberlite is taken over the surface for further processing.

The actual diamonds need to be separated from the rock surrounding them. The first step is milling and crushing the excavated material but this is accomplished in rudimentary firm to prevent any possible damage of potential gems inside.

A gravity-based device is used to classify the portion that contains diamond from the tailings. There is also another method of unveiling the diamonds is the use of media separators. The slurry is made u of water added into the crushed tailings and concentrate. It may be place into one of the three types of media separators. The first one is a cone-shaped tank that has an agitator that moves around the sides of the tank, but leaves adequate room in order for the lighter tailings to rise to the top and heavier elements sink into the bottom.

After that, the concentrate transports into the greasing area. The mixture of the kimberlite and diamond is mixed with water and is placed on greased table or belt. The device is vibrated and slanted. The method operates on the premise which the diamonds newly excavated will not be wet when they are brought in contact with water. Petroleum jelly is the preferred substance on a grease table or belt.

The chunks of diamond will eventually become small, impeccable shaped gemstones used commonly in jewelry, specifically engagement rings. Diamond dust should be used when it comes to cutting the stone. In cutting, miniscule groove is incised to the diamond surface and inserted with a cleaving iron. With a forceful and quick blow, the diamond perfectly split along the naturally occurring planes.
