Diamonds are so long lasting that no marriage can out live them - so it is said and believed. It was around 800 B.C. that diamonds began to be mined in India. The value of a diamond used to be ascertained by its ability to reflect light. From time memorable, diamonds have been considered as a good luck charm and having the ability to ward off evil spirits.
One of the myths floated by mine owners was that diamonds were poisonous. This was to ensure that the mine workers do not steal diamond by swallowing them.
Each diamond takes over three billion years to transform into this rare transparent form of pure carbon. Since this crystallization occurs at a very high temperature and pressure, it necessarily takes deep within the earths crust. The effect of heat and pressure at depths over 200 km results in the formation of diamonds.
They come to the surface of the earth along with the hot magna shot out by volcanoes. The oldest part of the continent is the place where they are generally found.
Diamonds may as well be found in areas where Red Garnets are found. This is because the Garnet also goes through a similar process to be formed.
Diamonds may surface at other places too. At times the inner earth crust is brought to the surface due to collision of Teutonic plates of the continents. The diamonds may also come up along with the crust. The great pressure generated due to impact of meteors may also cause diamonds to form. Diamond has derived its name from the Greek word for unconquerable, because of its strength and as it is unbreakable.
A beautiful one-carat diamond comes from 250 tons of are that has been mined and processed. Today, around 25 countries supply the world with diamonds, with the majority coming from Africa, Russia, Australia, and Canada. South Africa is a great source of luxury diamonds.
Mining for Diamonds
Some of the places where diamonds can be mined and the various forms of mining are:
- Around dried ancient waterways and present rivers (also called dry digging)
- In sand and gravel (also known as wet digging)
- Marine and beach deposits
- Open pit mining
Diamonds are extensively used in all walks of life and industry. While about 20 percent of mined diamonds are used in jewelry, the rest are used in the industry. Some industrial uses are as drill bits and cutting tools, in machinery, mineral services, stone and ceramic products, abrasives, construction, and transportation equipment.
Diamond truly is a possession that lasts for ever.
