How is a diamond made in nature?

Answer 1

A diamond is an allotrope (a form) of the element carbon. Other forms of carbon include graphite, which is the substance in pencil lead. A link is provided to the Wikipedia articles on diamond and on carbon.

Answer 2

Diamonds are formed as an allotrope of the element carbon, at depths greater than 90 miles. The pressure and heat at this depth was critical to the formation of the diamonds that are mined at the surface today. At crustal pressures, the stable form of carbon is the allotrope graphite.

Diamonds were transported to the surface by supersonic volcanic eruptions that carried molten rock material from the mantle containing diamond and other mantle minerals. Diamond is not formed from metamorphosed coal, and most diamonds discovered on the surface in mining operations are at least one billion years old; some may be two or three times that age. Diamond can also be formed from the pressures of high speed impacts of meteors with the Earth, but these are more of scientific interest, having no economic usefulness due to their small size and dispersion.
Intense pressure over time acting upon carbon.
When the LAva becomes hard and the volcano is empty you can chain saw it open a nd find a dimond

Answer 3

Essentially diamonds start as simple ash, charcoal, or other concentrated carbon material. From there two paths can be taken, the classic and first process was to place the carbon material into a chamber where they were heated intensely under extreme pressure which rearranged the carbon molecules into much more organized form. The other method is a new method devised by a team of researchers lead by Russell Hemley, of Carnegie Institute of Washington. This method, known as CVD (chemical vapor deposition), uses microwave radiation to heat a hydrogen plasma to 2200 degrees celcius at relatively low pressure to make much larger and finer diamonds than the traditional method. So efficient and cheap is this method that it is being considered for use in optical lenses in which laser transparency is neccesary.

Answer 4

well... most natural diamonds are formed 160 kilometers below earth in the mantle under high pressure and extremely high temperatures but it isn't a fast process to make it takes up-to 3 billion years to make.

BUT... if you are talking about man made diamonds or synthetic diamonds which is said to be created by a high pressure high temperature method. now there is this machine that is called a (belt press) that can make them. And there is another method called chemical vapor deposition (CVD) that is said to make them as well.

Answer 5

the same thing. carbon. diamonds is just carbon that is super heated and supercompressed.

Answer 6

people mine and then they form and 20 years later you go into the same cave and you will find dimonds!!

Answer 7

Diamonds are made in nature when coal is compressed with enormous pressure over thousands of years.

Answer 8

A diamond is made of compressed carbon,. The carbon atoms are arranged in a way that makes a diamond the hardest substance on earth.

Answer 9

I think it is made of carbon
