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

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