It is found in rock VERY deep into the Earth which has been under an enormous amount of force for roughly one million years. It is also 100% Carbon, the same as Coal, so it is possible for Coal to be replaced by diamond.
But I doubt you will live to see it! :P
Diamonds form deep underground due to carbon remains of dead trees etc being put under immense pressure. Sometimes they can be found closer to the surface of the Earth due earthquakes etc moving them closer to the surface.
Another Answer
Diamonds are formed deep within the earth's mantel under immense pressure and extreme heat. Diamonds surface upon eruption through volcanic pipes.
One hundred percent of the world's diamonds come from a depth of between 140 to 180 km within the earth's mantle and are erupted to the earth's surface by way of volcanic pipes.
Only one in 200 of these pipes produces diamonds. Volcanic pipes are being mined today in many countries in Africa -- Botswana being the largest producer there -- and in Canada, India, Brazil, Russia and Australia.
India or that general area. From the ground.
Diamond is an allotrope of the element carbon.
diamond is made of carbon
Diamonds form when they're under high pressure.
Diamonds are able to form in the Earthâ??s mantle. This is because there is carbon and great amounts of heat and pressure.
Overburden or lithostatic pressure.
The vast majority of diamonds form within the Earth's lithospheric mantle at depths of around 150 to 190 km. Volcanic pipes bring them to the surface with kimberlite or lamproite in the pipes. Diamonds are formed from carbon.
Overburden or lithostatic pressure.
The possessive form for the plural noun diamonds is diamonds'.Example: I had the diamonds' settings checked by a jeweler.
Diamonds are the crystaline form of Carbon.
No, diamonds are formed from carbon.
No form of chocolate contains diamonds.
Diamonds form when they're under high pressure.
Diamonds are a form of crystalline carbon which is an element.
Dust from diamonds is generated when diamonds are cut and polished.
Yes, diamonds are a form of carbon.
Diamonds can form slowly under deep pressure, or they can form very rapidly like when a volcanic eruption occurs.
Pave is a form of setting, and any gemstone can be set in this form, including diamonds with -- or without -- inclusions.
Graphite and diamonds
Diamonds are able to form in the Earthâ??s mantle. This is because there is carbon and great amounts of heat and pressure.
