Diamond
All minerals can be scratched if you used the right scratcher. Diamond can only be scratched by another diamond, and is most resistant to being scratched. In the jewelry world any thing harder than a 7 on the Mohs hardness scale is consider resistant to scratching.
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.
Geologists focus on the hardness property of minerals when they perform scratch tests. This test helps determine the resistance of a mineral to being scratched by another material, which can be indicative of its mineral type.
No, the streak is the color of a mineral when it is crushed to a powder form and pulled across an unglazed porcelain plate. This helps in identifying minerals as some minerals have different colors on their streak compared to their natural color.
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.
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.

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.

Hardness is the ability of a mineral to resist being scratched. A diamond is the hardest mineral--which means that no other mineral can scratch it.

Hardness refers to various properties of matter in the solid phase that give it high resistance to various kinds of shape change when force is applied. Hard matter is contrasted with soft matter.
