That would be its Mohs hardness.
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.
The resistance of a mineral to being scratched
A rock's hardness is its resistance to scratching or abrasion. This is commonly measured using the MOH's scale of hardness.
A mineral's resistance to being scratched is known as it's hardness. You can determine hardness by scratching it with another material whose hardness is already known. If it can be scratched, then the hardness is lower. If the unknown leaves a scratch on the known material, then its hardness is higher.
The hardness
The resistance to being scratched is known as hardness. Hardness is a measure of how well a material can resist scratching or abrasion. It is commonly measured using the Mohs scale of mineral hardness.
Diamond is the most resistant to being scratched as it is the hardest mineral on the Mohs scale with a rating of 10.
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.
