    Hardness is one of the better properties of minerals to use for identifying a mineral. Hardness is a measure of the mineral& 82 7;s resistance to scratching. The Mohs scale is a set of 0 minerals whose hardness is known. The softest mineral, talc, has a Mohs scale rating of one. Diamond is the hardest mineral and has a rating of ten. Softer minerals can be scratched by harder minerals because the forces that hold the crystals together are weaker and can be broken by the harder mineral.
