Clinohumite and Alexandrite Chemical Formula
While comparing Clinohumite and Alexandrite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Clinohumite and Alexandrite chemical formula.

Clinohumite and Alexandrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Clinohumite and Alexandrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Clinohumite and Alexandrite Optical Properties during the identification of gemstone. Specific gravity of Clinohumite is 3.69-3.81 whereas that of Alexandrite is 3.69-3.81.
