How long does it take for coal to turn into a diamond?
The Natural Diamond Process Due to the immense pressure that is present in this part of the earth, as well as the extreme temperatures, a diamond gradually begins to form. The entire process takes between 1 billion and 3.3 billion years, which is approximately 25% to 75% of our earth's age.
Does coal turn to diamonds?
Diamonds aren't an Earth-bound phenomenon, by the way. King also points out that some nano-scale diamonds have been found inside of meteorites. But there's no coal in outer space, so once again these tiny diamonds were probably formed by pure carbon. So no, it turns out that coal can't be turned into diamonds.
How is a diamond created?
Simply put, diamond formation occurs when carbon deposits deep within the earth(approximately 90 to 125 miles below the surface) are subject to high temperature and pressure. Some stones take shape in a matter of days or months, while others take millions of years to materialize.
What type of rock is diamond found in?
kimberlite Diamond is only formed at high pressures. It is found in kimberlite, an ultrabasic volcanic rock formed very deep in the Earth's crust.
How diamond is formed?

What type of rock is diamond?
igneous rock 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. The stone's unique hardness is a result of the densely concentrated nature of the carbon chains.
Is diamond found in coal mines?
In addition to the carbon, intense heat and pressure come together under the surface of the earth's mantle to create natural diamonds. While coal is also made of carbon, it contains lots of other impurities that make it impossible from diamonds to form out of coal.
How is diamond found in nature?
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. The second geological source for diamonds is placer deposits.

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 is diamond made naturally?

Where did diamonds come from?
It is believed that diamonds were created millions of years ago, with some dated even older than the Earth's first land plants. They are formed from applying extreme heat and pressure to graphite which lays deep in the Earth's core (also known as the mantle), which is around 150km-200km below the Earth's crust.

The majority of all pink diamonds mined come from one source in Australia, the Argyle Mine. Argyle Pink Diamonds are so expensive because of the very limited supply. A pink diamond is formed of only carbon like a white diamond, through millions of years in the kimberlite pipes of volcanoes.
Is black diamond rare?
Although most black diamonds on the market today are either superheated or irradiated to an almost black color, natural black diamonds do exist, though they are extremely rare. Carbonados, sometimes called “black diamonds,” are a distinct and unusual polycrystalline diamond material.
