Mohs Scale of Relative Mineral Hardness

Sandstone 6-7; Granite 6-7; Natural Quartz 7; The hardness of material is measured by determining which material can scratch or be scratched by others, if they can scratch one another then they are the same hardness. For example if a given material is scratched by Corundum but not by Diamond, its hardness on the Mohs scale is 9.5.
