A mineral cannot be organic. A mineral cannot be made by or composed of life forms.
Diamond is the hardest naturally occurring mineral and can scratch all other minerals. Talc is the softest of minerals and cannot scratch any other mineral.
A mineral must follow a certain criteria. It has to be naturally occurring, generally inorganic homogeneous solid with a crystalline structure and a definite (but not fixed) chemical composition. Water cannot be a mineral because it is a liquid. Honey cannot be a mineral because it is a liquid and is organic Oxygen cannot be a mineral because it is a gas. Teeth cannot be a mineral they are organic. Ice, however, can be a mineral if it is formed naturally. Ice forming on your windshield is a mineral but ice from an ice cube tray is not a mineral.
Corundum- which can only be scratched by diamond. Diamond cannot be scratched by any other mineral.
A diamond is the only material that cannot be scratched by any other than itself.

A diamond. Actually, a diamond can be scratched my other minerals.
