Diamonds are mined in extremely hazardous conditions. That is also one of the main reasons why the precious gemstone has a hefty price tag attached to it. Some of the highlighters on how diamonds are being produced are stated below:
- The process of diamond creation actually begins with the fields being dug as much as 100 miles below the earth’s surface. It is the immense pressure and heat, by which carbon atoms crystallize to form a rare form of gemstone called ‘diamond’.
- Then diamonds are made to arrive at a rough surface, and a volcanic eruption arises due to the tremendous heat and pressure found in the earth, dug far below. The eruption is also known as a kimberlite eruption. A previous eruption of a similar kind arose as early as 100 million years ago.
- In order to discover kimberlite eruptions, Geologists use termite pipes. The process reveals specific volcanic rocks where there is huge amount of diamonds.
- Not many of you realize the hazardous and tight environmental conditions under which diamonds are extracted. To reach the bottom most portions of the kimberlite pipes, the rocks are blasted and this method used to mine diamonds is known as pit-mining. Hydraulic shovels and heavy machinery need to be used in order to thaw the rocks rip open and discover diamonds located far deep below.
- In regions where one can find diamonds near a thinner layer of sand and gravel, an easier method of excavating diamonds is used. The method is known as ‘open pit’ mining.
- On the other hand, it is the underground mining, which is the most complicated way of extracting the precious gemstones. This method depends on size, shape and nature of kimberlite deposit found.
- You can also extract diamonds from sea-beds. This form of diamond mining is known as marine mining.
- Now that diamonds are extracted, these need to be processed. The first step in processing of hard core carbon atoms is known as comminution, i.e. breaking up of the ore by crushing and milling.
- Once the ore has been crushed, it is mixed with ferrosilicon using dense medium separation, known as DMS.
- As the diamonds repel against water and are subject to grease, they are made to pass via the diamond belt.
- The rough diamonds are measured and categorized into several types, before they are actually cut.
- These are sorted on the basis of color, size and clarity.
- Diamonds now have to be cut and sawed. There are several instruments and machinery, to get the job done.
- Examiners have to constantly keep checking the various facets of the diamond stone. The process in creation of diamonds goes through several checks of quality.
- Each diamond stone is examined using a microscope, to check on its clarity.
- Finally the diamonds are manufactured in several shapes and colors to make intricate jewelry and sold to diamond showrooms across the world.
This is how the diamonds are mined, crushed and then are sewed and then are cut and polished before being sent across for the making of intricate jewellery.
