Can diamonds form anywhere?

Almost all commercially minable diamonds are formed in an area of the earth’s mantle about 150 kilometers below the surface. This area is often known as the diamond stability zone, where temperatures are above 1000 degrees Celsius.

Can diamonds be found anywhere?

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.

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.

Can you find diamonds in gravel?

After sifting in water, the saruca is flipped upside-down on a table, so that heavy gravel (and hopefully a diamond) appears on top of the resulting gravel pile. … Diamonds are fairly heavy for their size and are often found near other heavy rocks and minerals, such as jasper, hematite, calcite and quartz.

What type of soil are diamonds found in?

A grove of Pandanus candelabrum, which appears to grow only in diamond-bearing kimberlite soils. Diamonds are formed hundreds of kilometers below the surface, as carbon is squeezed under intense temperatures and pressures.

How far beneath the earth’s surface do diamonds form?

Natural diamonds typically form 150–200 km below the surface of the earth. Diamond formation does not occur everywhere at these depths, but only below the oldest continents that have been stable for billions of years; these areas are known as cratons (see figure 2 in Summer 2018 Diamonds from the Deep).
