It has a crystal structure.

Explanation:

Minerals occur naturally and are generally common and are defined by several factors. They are crystalline inorganic compounds, this means that their structures are made up of orderly, repeated atoms in a regular geometric arrangement, and they are not comprised of living things. These compounds are solid at room temperature and often made from natural geologic processes. Furthermore, their structures are comprised of a definite chemical compound and their atomic ratios stay the same.
