Formation of Minerals. Minerals form when atoms bond together in a crystalline arrangement. Three main ways this occurs in nature are: 1) precipitation directly from an aqueous (water) solution with a temperature change, 2) crystallization from a magma with a temperature change, and 3) biological precipitation by the action of organisms. Precipitation from aqueous solution

Mohs Scale was developed in 1812 by German mineralogist Friedrich Mohs () Mohs Scale of hardness is a RELATIVE scale, not proportional.

However, any breakdown of the crystal can change the mineral hardness. For example, feldspar crystals often break down or are replaced by clay minerals, causing the mineral to appear less hard. For further complexity, some minerals have different hardness for different sides of the crystal due to differences in how the atoms are bonded together. For example, kyanite has a hardness of 4 on one ...
