Diamonds are formed deep within the earth's mantle, under very high temperatures and very high pressures: generally more than 90 miles below the earth's surface, and hotter than 2,000 degrees F. The formation process takes millions of years to complete.
Kimberlite is the igneous rock type that is formed in the same environment as diamonds -- formed from liquid core material.
The incubator for all these formation phenomenon reveals itself in the kimberlite pipes that can contain diamonds -- not all do.
Since kimberlite pipes have been identified by scientists as a phenomenon, none has erupted to the earth's surface.

What geological material are diamonds found in?
Kimberlites and lamproites.
What type of ultramafic rock sometimes contains diamond?
Kimberlites are the rock type that diamonds are usually found in. They are formed when a magma from deep in the mantle drills its way to the surface in a fast gaseous explosive event. Diamonds typically occur as xenocrysts within the Kimberlite matrix. the volcanic deposits are called Lamproite igneous volcanic pipes. Please see the related links.
What is the type of magma that carried most diamonds to the surfaces?
Diamonds are brought to the surface in two main magma types with fairly extreme compositions. These are: Kimberlites and Lamproites. You can read more about them, below. Volcanic pipes that blast diamonds to the earth's surface, also erupt garnet xenoliths onto earth's surface. Only about one in every 200 such pipes contain diamonds. You can read more about the exploratory geology, below.
What causes the pressure that allows diamonds form in the mantle?
Diamonds are believed to be formed about 90 miles below the surface of the Earth, in the mantle. So, the weight of the Earth above them creates the pressure to form diamonds.
What happens when carbon atoms form under extreme pressure?
Sometimes, diamonds form.
What geological material are diamonds found in?
Kimberlites and lamproites.
Diamond falls under which category of rocks?
Igneous rocks are the category of rocks that contain diamonds. The two types of igneous rocks that form diamonds are kimberlites and lamproites.
What type of ultramafic rock contains diamonds?
Diamonds are found in rayer types of igneous rocks known as "Kimberlites"credit to Alberto Vacca
Why do scientists theorize that kimberlites originate deep within the earth crust or mantle?
because diamond and other minerals found in kimberlites can form only under very high pressures
Can diamonds be found in rocks or clay?
The source of diamonds is an igneous rock called Kimberlite. However when Kimberlites are eroded the diamond may survive in the sediments and may be incorporated in a clay - however while this may happen I do not know of an example.

What is the possessive form of the word diamonds?
The possessive form for the plural noun diamonds is diamonds'.Example: I had the diamonds' settings checked by a jeweler.
Diamonds are pure form from what element?
Diamonds are the crystaline form of Carbon.

Do diamonds form from iron?
No, diamonds are formed from carbon.
Does chocolate contain diamonds?
No form of chocolate contains diamonds.
Do diamonds form under high or low pressure?
Diamonds form when they're under high pressure.
