A specific, crystalline form of carbon is the only element in diamond
Diamonds are a crystalline form of pure carbon.
Natural diamonds are composed of carbon. Any chemical used on a diamond may enhance it, and thus lower its value.
Chemical and physical changes depends on the chemical compostion.
is a soils
it is the gas that is making the core
You think to chemical compostion or to stoichiometry.
People who want to change the colour of a diamond use radiation, not a chemical.

Its compostion is usually rocky or metallic.
the change in the social compostion of rural population
Not sure, but diamond are igneous rockand is intrusive.
If you think to diamond as a carbon allotrope, the chemical symbol of carbon is C.
No, a simulant diamond is not a real diamond. It is a material that mimics the appearance of a diamond but is not made of the same physical and chemical properties as a natural diamond.
Cutting a diamond is a physical change. It involves breaking the diamond into smaller pieces through mechanical means without altering the chemical composition of the diamond itself.
