the mohs scale of mineral hardness is based on the ability of one natural sample of mineral to scratch another mineral visibly. the samples of matter used by mohs are all different minerals. minerals are chemically pure solids found in nature. rocks are made up of one or more minerals. as the hardest known naturally occurring substance when the scale was designed, diamondsare at the top of the scale. the hardness of a material is measured against the scale by finding the hardest material that the given · text under ccbysa licensemohs hardness scale testing the resistance to being scratchedthese crystals have a hardness of about 5 if they are tested parallel to the long axis of the crystal, and a hardness of about 7 if they are tested parallel to the short axis of a crystal. why? these different directions encounter different bonding environments in the kyanite crystal.
