WebDiamond is the hardest known mineral, Mohs' 10. Notes: It must be noted that Mohs' scale is arbitrary and non-linear, i.e. the steps between relative hardness values are not necessarily equal. Rather, it is a method of gauging the relative hardness of a mineral. WebIdentifying minerals by physical properties. The most common minerals in Earth's crust can often be identified in the field using basic physical properties such as color, shape, and hardness. The context of a mineral is important, too – some minerals can form under the same conditions, so you are likely to find them in the same rock, while others form under …
