    Hardness in minerals can vary due to impurities, but is usually diagnostic. We determine the relative hardness of minerals using a scale devised by mineralogist Friedrich Mohs. The scale assigns hardness to ten common index minerals, and is based upon the ability of one mineral to scratch another.
