Description: These Moh's hardness scales contain the 9 primary minerals of the Mohs hardness scale (excluding diamond) mounted on an identification plaque. A Mohs Hardness Scale sample kit is a collection of reference minerals with known hardness values, typically ranging from 1 (the softest) to 10 (the hardest), used to test and compare the hardness of unknown materials.  Users can scratch the materials with one another to determine the relative hardness of a substance based on which minerals can scratch others. Determination of hardness can be an important step in the identification of a mineral.
