Hardness is the measure of how easily a mineral is scratched.
hardness define minerals
The Mohs Scale of Hardness determines the hardness of minerals by scratching them with commonly found objects. The minerals are assigned a number which corresponds to their hardness; higher numbers indicate higher hardness.
The hardness of MINERALS.
Relative hardness is the property of minerals that uses the Mohs scale for classification.
The Mohs Scale is what is used to measure the relative hardness, or scratch resistance, of minerals. Mohs hardness often agrees with absolute hardness, which is another way of measuring the relative hardness of minerals.
Some minerals have varying hardness according to the direction you may scratch

Granite is not assigned a number on the Mohs scale of hardness. The Mohs scale is a measurement of the relative hardness of minerals. Because granite is a rock composed of a variety of minerals, only the individual minerals which compose it have a Mohs hardness.
