The hardness of a rock is identified using Mohs Scale of Hardness. Certain rocks and minerals have a predetermined hardness level based on this scale, which uses the obvious logic that if something scratches something else, then it must be harder than that which it scratches. Likewise, if something doesn't scratch something else, it must be softer than that which it cannot scratch. Using a scale from 1 to 10, common objects can be used to determine hardness level. A fingernail, for example, has a hardness of 2.5. Any rock that can be scratched by a fingernail (talc, for example) has a hardness less than 2.5. A streak plate, which is commonly used for hardness tests, has a hardness of 6.5. Diamonds, the hardest minerals, define the 10 on the hardness scale. Using these common objects and their related hardnesses, one can easily identify the rock in question.

How hard are instrusive rocks on the mohs hardness scale?
The highest level on the Mohs hardness scale is a level ten. Diamonds are at a level ten and are also intrusive rocks. However Intrusive rocks can be at almost any level of hardness based on the minerals the rock contains.
