The most used relative hardness scale. It's a simple comparative scale but can also be misleading. For example, there is a very large gap between Sapphire, 9 and Diamond 10 in actual hardness.

Mohs Scale of Hardness in Geology

The Mohs Scale of Hardness is a relative scale used in geology and mineralogy to determine the scratch resistance of minerals. It was developed by German mineralogist Friedrich Mohs in 1812 and ranks minerals from 1 to 10, where 1 represents the softest mineral, Talc, and 10 represents the hardest, Diamond. A mineral with a higher Mohs hardness can generally scratch a mineral with a lower hardness. The standard scale includes Talc (1), Gypsum (2), Calcite (3), Fluorite (4), Apatite (5), Orthoclase (6), Quartz (7), Topaz (8), Corundum (9), and Diamond (10). The Mohs scale is widely used for mineral identification, geological fieldwork, and studying rock and mineral properties.
