Where the diamonds come from?

The great Moguls of India, who were the first to date large quantities of diamonds on their territories, acquired immense fortunes thanks to these gems.

It was not until the 17th century that Europe in turn experienced a great craze for these stones that only the powerful could afford.

But the deposits of India began to run out, and the European nations searched the soil of their recent colonies to discover this new source of wealth.

In the middle of the last century, many thought that the world's diamond reserves had been depleted.

It was then that in 1866 the first diamond of South Africa was discovered and a new rush began.

Today, Southern Africa is the world's largest diamond producer. There are also diamonds in other parts of Africa, South America in Russia.


How do we extract diamonds?


No one knows exactly how diamonds were originally created. All that can be said is that millions of years ago, under the action of temperature and gigantic pressure, the carbon crystal was transformed deep into the earth into diamond crystals. .

Subsequently, the magma that enveloped the diamonds was projected to the surface through fissures similar to the throat of a volcano. Erosion cleared diamonds from their gangue and these were dragged by rivers to form silty deposits.

Modern mining methods include open-cast mining, extraction of marine terraces, and of course the more traditional mining process of fetching ore buried deep underground through volcanic vents. This bluish ore is called Kimberlite. It is crushed and washed until a rich diamond residue is obtained. The diamonds are then separated from the residue after passing over grease-laden tables or using an X-ray separator. They are then sorted according to their shape, color and size.

Of these rough diamonds, only 20% are likely to become jewelery stones. The remaining diamonds are used in the industry.

In order to obtain the equivalent of one carat of polished diamonds, it is necessary to treat some 30 tons of kimberlite. One carat weighs 0.2g.
