For example, if some material is scratched by topaz but not by quartz, its hardness on the Mohs scale How hard is tourmaline on the Mohs scale?,Hardness and toughness But the Mohs scale is deceptive. The steps between the minerals are not evenly spaced. For example, diamond is only one number away, but it's many times harder than gems in the corundum family. Turquoise ranks 5 to 6 on the Mohs scale and its toughness is generally Fair to Good.
