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.

What type of rock is diamond found in?
Background. The diamond is the hardest natural substance known. It is found in a type of igneous rock known as kimberlite. The diamond itself is essentially a chain of carbon atoms that have crystallized.
Do diamonds come from coal?
Over the years it has been said that diamonds formed from the metamorphism of coal. According to Geology.com, we now know this is untrue. “Coal has rarely played a role in the formation of diamonds. ... The diamonds form from pure carbon in the mantle under extreme heat and pressure.
Where are diamonds found in the ground?
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.
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.
Can diamond be found in quartz?
Diamonds have a specific gravity of 3.1–3.5. Quartz has a specific gravity of 2.6–2.7. In placer deposits, tumbled quartz pebbles and diamonds can appear similar.
How can you tell if a rock is a diamond?
The only hardness test that will identify a diamond is scratching corundum. Corundum, which includes all rubys and sapphires, is 9 on the hardiness scale. If your suspected diamond crystal can scratch corundum, then there is a good chance that you found a diamond. But NO OTHER HARDNESS TEST will identify a diamond.
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).
Can coal turn into diamond with peanut butter?
The coal has become a crystalline diamond. ... To change the crystal structure of coal, you would need over 1000 times atmospheric pressure, at temperatures over 1000℃. Given the right conditions, it's certainly possible to turn peanut butter–a carbon-rich material–into diamonds.
Can diamonds be found in rivers?
Diamonds are found naturally in Kimberlite rocks or alluvial deposits. ... These rocks are carried by rivers, streams and waterfalls and diamond crystals are deposited in the water hence the pacer or alluvial deposits.
What type of rock is gold?
Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides.
Can I keep a diamond I found?
If you ever find a diamond ring, or any lost property, don't assume that you can keep it. Always attempt to find the owner if possible, or turn the item in to the police. ... So, unless you're at Crater of Diamonds State Park, you cannot keep a found diamond.
What does diamonds look like in the ground?
The place is called Crater of Diamonds State Park and more than a hundred visitors have already picked up some pretty nice diamonds. That includes a teenager who found one of the biggest diamonds yet! Diamonds are generally found where rocks like kimberlites are found (sometimes along with other gems.)
What kind 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.
Can you break a diamond with a hammer?
As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. Whether something is hard or strong depends on its internal structure. ... Diamonds, because of their lack of flexibility in the structure, are not actually very strong at all.
Are raw diamonds worth anything?
With few common inclusions, raw diamonds are more valuable than diamonds with several common flaws. A raw diamond which has a brownish or yellowish tint is stronger but less valuable. On the other side, diamond with less hue is far more valuable. Transparent and colorless diamonds are too rare to find.
Can you find a diamond in a geode?
Typically, geodes do not have gold or diamonds in them. ... Geodes are known to contain gems called Herkimer diamonds, Bristol Diamonds as well as Gold aura quartz, but they are not real gold or diamonds. Although certain quartz rock deposits have gold, it is different from the quartz crystals commonly found inside geodes.
