Mohs scale of mineral hardness Wikipedia

The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.

The problem with Mohs'' scale is that natural diamond is extremely hard, as its value on the Knoop microhardness scale clearly shows (Table 3, Fig. 4a). When Mohs'' scale is plotted against the log of indentation hardness, minerals 2 to 9 on Mohs'' scale make an approximate linear relationship (Fig. 4b).
