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.
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
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.
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.
the same thing. carbon. diamonds is just carbon that is super heated and supercompressed.
people mine and then they form and 20 years later you go into the same cave and you will find dimonds!!
Diamonds are made in nature when coal is compressed with enormous pressure over thousands of years.
A diamond is made of compressed carbon,. The carbon atoms are arranged in a way that makes a diamond the hardest substance on earth.
I think it is made of carbon
Diamond
Diamond is an allotrope (arrangement) of carbon.
No.
No a diamond is a mineral. It is made out of one substance. Diamond :P
diamond is the hardest and graphite is the softest
Mother Nature made the world's biggest diamond.
Mother Nature made the Cullinan diamond, which was discovered by a human in 1905.
Mother Nature made that stone.
Mother Nature makes natural diamonds.
a diamond is nature made from immense pressure over a very long time. A cubic zirconia is man made of a white crystalline substance to look like a diamond. A real diamond will cut glass. The latter will not.
graphite and diamond
No. Natural chocolate diamonds are made by Mother Nature in a way that gives them their chocolate colour. However, there are man-made chocolate diamonds.
A ruby is a ruby; a diamond is a diamond. They are different gemstones. Both occur in nature.
Pure is variable and can be used to define the flawless nature of a diamond.
Harold Diamond goes by Nature Boy.
One of the hardest substances found in nature is the diamond. One of the strongest man made materials is called graphene.
