Where are diamonds found most?
Diamonds are present in about 35 countries. South Africa, Russia and Botswana are the main producers of gem diamond while Australia produces most of the industrial diamond. They are also found in India, Russia, Siberia, Brazil, China, Canada and the United States.
Where are diamonds found naturally?
The following countries produce industrial grade diamonds: Australia, Botswana, Brazil, China, Congo, Russia and South Africa. Geologically speaking, natural diamonds are found in two environments. Most are found in kimberlites, which are pipe-like formations created as a result of volcanic and tectonic activity.
Which continent has most diamonds?
Africa. Together, Africa’s diamond-producing countries mean that Africa is the world’s first diamond area representing more than 60% of the global diamond production.
When did diamonds come to Europe?
An ancient love for diamonds
According to most theories, man first came across diamonds in the land of India. At first, diamonds were therefore only traded in India. But after Alexander the Great brought the first diamonds to Europe in 327 BC, the public and especially elite fell in love with the gem in no time.

Which country found diamond First?
The earliest diamonds were found in India in 4th century BC, although the youngest of these deposits were formed 900 million years ago. A majority of these early stones were transported along the network of trade routes that connected India and China, commonly known as the Silk Road.
How do I find diamonds in my yard?
You can look through the alluvial deposits of sand and mud from old river and stream beds to pan for diamonds by using methods that include scanning the surface, sifting the soil, and then sifting the soil in water.
How deep diamonds are found?
Diamonds are found at a depth of approx. 150-200km below the surface of the Earth. Here, temperatures average 900 to 1,300 degrees Celsius and at a pressure of 45 to 60 kilobars (which is around 50,000 times that of atmospheric pressure at the Earth’s surface).
What rock is diamond found in?
Diamond is only formed at high pressures. It is found in kimberlite, an ultrabasic volcanic rock formed very deep in the Earth’s crust. The extreme pressures needed to form diamonds are only reached at depths greater than 150km.
Why are so many diamonds found in Africa?
Diamonds in Africa were formed somewhere between 600 million and 3 billion years ago when titanic-force pressure and heat caused carbon 1,200 miles (1,931 km) below the Earth’s surface to crystallize. As recently as a million years ago, erupting molten rock brought the diamonds closer to the Earth’s surface.

Which country has the best quality diamonds?
Today, Russia is the world’s leading producer of gem-quality diamonds on the basis of carat weight and has held that position for over a decade. Botswana is the only country that has a higher production value – mainly because its production includes a high proportion of large, high-quality diamonds.
Where do diamonds go after they are mined?
Q: After the diamonds are sorted and sold, what happens to them? 90% of the world’s diamonds then travel to China or India to be cut and polished. It takes 2-3 weeks for this process and then it is ready to be certified by one of the world’s gem laboratories.
How did humans discover diamonds?
Diamonds were discovered in the pans of gold miners as they sifted through the gravels of local rivers. Once it reached its full potential, Brazil dominated the diamond market for more than 150 years. While sources changed, the diamond market experienced its own evolution.

THE HISTORY OF DIAMONDS
The story of diamonds in South Africa begins between December 1866 and February 1867 when 15-year-old Erasmus Jacobs found a transparent rock on his father’s farm, on the south bank of the Orange River.
