What is the purpose of a diamond?
Diamonds per se have no purpose; diamonds do, however, have uses. Diamonds can be used as adornment, or in industry.
Why did they make diamonds?
Diamonds Were Never Made, They Are A Natural Substance. However in more recent times, it is possible to produce a synthetic diamond by the compression or carbon, however it is very expensive.
If you freeze graphite is it still toxic?
Graphite cannot be "frozen" since it is already a solid. However, cooling it does not decrease the toxicity, it only makes it colder - this can cause problems if you consume it on its own.
Is Graphite an Ionic Compound?
No, it is a pure form of the element carbon composed of sheets of covalently bonded atoms.

Do diamonds conduct electricity?
they don't conduct electricity: they have no free electrons. graphite, however, made of the same stuff as diamond (carbon) has a different structure, which means that it does have free electrons, and a lot of them. Therefore graphite is a good conductor of electricity.
Why blue diamond can conduct electricity?
Blue diamonds do not conduct electricity. Diamonds do, however, conduct heat, in fact five times better than silver. Both diamonds and graphite are produced naturally from carbon. Diamond is an excellent electrical insulator, graphite is a good conductor of electricity.
Carbonate minerals contain?
Some minerals contain carbon, such as graphite and diamonds, however while they both contain carbon, the diamonds density is far greater.
Which is the best reason for the difference between the properties of diamond and graphite?
Graphite and diamonds are both network covalent carbon chains. The only difference is the structure of each. Graphite is very soft and is used as a lubricant, due to the fact that its carbon atoms are bonded together in layers which slide apart easily. Diamond, however, is very abrasive, because its carbons are all bonded to each other in a very rigid fashion.
Can diamond convert to graphite and vice versa?
Diamond (and also graphite) is pure carbon, without iron. Heating graphite and subjecting it to intense pressure can make small industrial diamonds.
Why are diamonds made from graphite not a mineral?
By definition, a mineral must form by natural processes. So anything man-made, even if it is chemically an structurally identical to a mineral, is not a mineral. However, natural diamond is formed from graphite as well.
Are diamond and graphite isotopes of carbon?
Yes, diamond and graphite are isotopes of carbon as they are both entirely made of carbon. However they have very different structures resulting in their different properties.
How are diamond and graphite made the same?
They are not made the same- but they come from the same element- carbon. However, carbon can take different crystal shapes. One of those is graphite, a very different one is diamond.
Is a black diamond valuable?
Natural black diamonds are rare. They are due to dark graphite inclusions. Their rarity makes them valuable. Most black diamonds are synthetic and made by heat treating low quality diamonds. The price of a synthetic black diamond is lower than that of white diamonds.
What would happen if you melted diamonds?
If you heated diamond in air it would turn to graphite - a more stable form of carbon - long before it melted. However, it can be melted if subject to 10 million times normal atmospheric pressure. When the pressure is reduced the diamonds will crystallised again. This has led scientists to speculate that there might be "seas" of molten diamonds on Neptune and Uranus because their atmospheres generate intense pressures and also are carbon-rich.
Does diamond wear away after years?
Diamonds are forever Diamonds are 'not' forever. They spontaneously react to form graphite (the stuff in your pencil), however, this takes a very long time. It is not something you will witness in your lifetime.
