Hardness.
The resistance of a mineral to being scratched
Diamond is the mineral that is most resistant to being scratched. It is the hardest known natural substance, scoring a 10 on the Mohs scale of mineral hardness.
Diamond is the hardest mineral and is most resistant to being scratched. It is ranked as a 10 on the Mohs scale of mineral hardness, making it the hardest naturally occurring substance.
The Mohs mineral hardness scale.
Mineral hardness measures the resistance of a mineral to scratching or abrasion. It is determined by the ability of a mineral to scratch another mineral or be scratched by it, as defined by the Mohs scale of hardness.

The resistance of a mineral to being scratched is known as its 'hardness'. This is a relative measurement determined by whether it scratches, or is scratched by, other materials of determined hardness. Hardness is measured on the Mohs scale. To give to some idea, diamond (the hardest known mineral) is a 10, while talc (the softest) is 1. A copper coin is around 3, a fingernail is around 2, an iron nail is around 5. Quartz, for example, is a 7.
Moh's hardness scale was used to determine a mineral's resistance to being scratched. The tendency of a mineral to break along smooth flat surfaces is cleavage.
Hardness measures a mineral's resistance to being scratched.
Diamond is the most resistant to being scratched as it is the hardest mineral on the Mohs scale with a rating of 10.
The most commonly known mineral that can be scratched by a fingernail is talc.
