Mineral - Mineral - Hardness: Hardness (H) is the resistance of a mineral to scratching. It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardness. The degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched by another or by a steel tool.

Mohs Hardness Scale (U.S. National Park Service) Oct 17, 2019 On the top end of the scale, a mineral with a hardness of 10 means that no other mineral can scratch it. Talc has a hardness of 1, and diamond has a hardness of 10. Mohs hardness scale is very useful for identifying minerals in the field.

Material Hardness - from Types of Hardness to Testing

The different types of hardness discussed above have different scales of measurement. For scratch, indentation, and rebound hardness, the measurement methods vary (e.g. Brinell, Rockwell, Knoop, Leeb, and Meyer). As the units are derived from these measurement methods, they are not suitable for direct comparison.
