The formation of natural diamond requires very specific conditions. Diamond formation requires exposure of carbon-bearing materials to high pressure, ranging approximately between 45 and 60 kilobars, but at a comparatively low temperature range between approximately 1652-2372 °F (900-1300 °C). These conditions are known to be met in two places on Earth; in the lithospheric mantle below relatively stable continental plates, and at the site of a meteorite strike.

∙ 15y agoDiamonds form about 100 miles (161 km) below the Earth's surface, in the molten rock of the Earth's mantle, which provides the right amounts of pressure and heat to transform carbon into diamond. In order for a diamond to be created, carbon must be placed under at least 435,113 pounds per square inch (psi or 30 kilobars) of pressure at a temperature of at least 752 degrees Fahrenheit (400 Celsius).

∙ 13y agoThe diamonds are made by the immense pressure of the Earth. The deeper you go, the more pressure, and the more diamonds you will find. If you want to make them bigger, just leave them under for a period of time

∙ 8y agoDiamonds are essentially compressed carbon but the method of mining and selecting the best quality is what makes them precious. When the carbon is at a very high temperature and under very high pressure, the bonds are formed. Natural diamonds are made 180km below the earth’s surface. The raw material extracted from the ground is then transported to a special screening plant for further processing. There's another form of alluvial mining called artisanal mining. The temperatures at this depth are between 1100o c and 1400o c. The diamonds are then cleaned up, cut and polished.

Where is diamond obtained?
By mining, or digging for them along volcanic pipes which are mostly kimberlite. You have to dig and sort through a lot of rock to find the diamonds. Diamonds can also be made in many other ways including man made but digging is still popular because the most valuable diamonds are those made by nature long ago.
Why diamonds are still considered minerals?
That is what they are. Diamonds are formed in the ground under pressure. It is made of carbon.
How are diamonds extracted from the ground?
Diamonds are mined.
Are pave diamonds made with inclusions?
Pave diamonds are not 'made'; pave diamonds are set. Diamonds are 'made' by Mother Nature deep within the earth's mantle under extreme high pressure and temperatures.. 'Pave diamonds' refers to the setting of the stones. Diamonds used in pave settings can be of any quality, so long as they are faceted. Most diamonds contain inclusions.
What do diamonds look like when they come out of the ground?
when diamonds come out of the ground they are rough and not as pretty as in jewelery stores
How much force is required to make coal into diamonds?
Diamonds are not made from coal. Diamonds are formed deep within the earth's mantle under enormous pressure and extreme heat, from carbon.
What are diamonds called that are made in factories?
Diamonds made in factories are called man-made diamonds.
How is diamond prepared?
Diamonds are made from carbon atoms, which are highly pressurized and under extreme temperatures in the earth. There are also ways to make diamonds in a laboratory.
Is coal and-or diamonds man made?
No. They where here before humans. However, in the 1950s, industrial diamonds were first made by scientists in a lab, and today, you can commission or purchase a man-made diamond. Not so much with coal. It's still dug from the ground.
When diamonds are in the ground what is the rock around it?
Some diamonds may be included in kimberlite.

What mineral do diamonds come from?
Diamonds are made from carbon, which is an element. They are made within "kimberlite" rock - I do not know if kimberlite is a mineral, or not. Sometimes, diamonds are washed out of kimberlite by the weather, and can be found in placer (PLASS-uhr) deposits, that is, at or near the surface of the ground. There are also diamonds found in meteorites that fell to Earth perhaps 3.5 billion years ago.
