Euclase and Biotite Chemical Formula
While comparing Euclase and Biotite 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 Euclase and Biotite chemical formula.

Euclase and Biotite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Euclase and Biotite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Euclase and Biotite Optical Properties during the identification of gemstone. Specific gravity of Euclase is 2.7-3.3 whereas that of Biotite is 2.7-3.3.
