You may be really surprised to know that Congo and Russia are world leaders in diamond production. But South Africa was the origin of the industry that gives us not only precious gems but resources for extremely durable tools and super diamond polishers.
Hardest mineral on Earth – the diamond, formed millions of years ago when the red-hot magma breaks through Earth’s surface, passing the carbon-rich rocks. These breakthroughs look like volcano tubes, so geologists call them “explosion pipes”, because the magma erupted from the depths like an explosion.
Some of these tubes are filled with clay-like rock bluish in color. On behalf of Kimberly – places in South Africa where it was first found – bluish clay is called “kimberlitic”. In this blue clay you may find the diamond crystals.
For many years the diamond deposits in South Africa were the only known, but in the middle of the 20th century situation changed and now there are 20 countries in world that produce different kinds of natural diamonds.
Nowadays South Africa takes the 5th place in world biggest diamond producers. At the top of the list you can see:
- Russia. http://www.e-mj.com/index.php/features/3237-diamond-mining-in-russia.html
Together, they produce approximately 5,000 million carats or 1,000 tones natural diamonds per year.
Besides “diamond pipes” there are others sources of diamonds. In Brazil, Indonesia, Australia, Africa and Russia it may be also found in stony placers along rivers. Most diamonds are mined in the open. Only in Africa there are still few operating shafts on kimberlitic pipes. To produce 1 kilo of row diamonds you have to dig 1 ton of ore.
Even the most beautiful diamonds have discontinuities and additives as result of pressure during the forming and interaction with the surrounding materials. The mineral supplements may indicate the origin of diamonds. For example tiny crystals of emerald chromediopside are typical for diamonds from Russia and South Africa. Some sources are characterized by streaks of graphite or other identifying details that will give to an expert enough clues to define its diamonds origin.
From the very top of pure jewel to the lowest grade of Bort, used for abrasive polishing, diamonds have their place in the modern world. 20 counties in the world provide a variety of quality diamonds for industry needs and jewelry.
