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.
What layer of the earth are diamonds found in?
All diamonds form within Earth’s mantle, but most form above that boundary layer.
Where is the best place to dig for diamonds?

Do diamonds form on Earth?
Diamonds were formed over 3 billion years ago deep within the Earth’s crust under conditions of intense heat and pressure that cause carbon atoms to crystallise forming diamonds. Diamonds are found at a depth of approx. 150-200km below the surface of the Earth.
How far in the earth are diamonds?
Diamonds are formed deep within the Earth about 100 miles or so below the surface in the upper mantle.

What can cut a diamond?
Diamonds are cut with specialized tools that make use of diamond tipped phosphor bronze or diamond dusted steel blades. Such tools are used to exploit the structural weakness of the diamond by grooving and striking along specific tetrahedral planes.
Why is diamond so hard?
The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.
