Bowenite and Dravite Chemical Formula
While comparing Bowenite and Dravite 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 Bowenite and Dravite chemical formula.

Bowenite and Dravite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Bowenite and Dravite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bowenite and Dravite Optical Properties during the identification of gemstone. Specific gravity of Bowenite is 3.03-3.18 whereas that of Dravite is 3.03-3.18.
