Question

is a diamond a mineral and why

Answer 1

A diamond is a special arangement of carbon atoms and belong to the group of native element minerals (i think).
Now i don't know the definition for minerals so i just use the wiki:
1.Naturally occurring
2.Stable at room temperature
3.Represented by a chemical formula
4.Usually abiogenic
5.Ordered atomic arrangement

All of the criterias is true for the diamond so I would say that could be an argument and conclution to say that a diamond is a mineral.

Answer 2
