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

Dravite and Bronzite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dravite and Bronzite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dravite and Bronzite Optical Properties during the identification of gemstone. Specific gravity of Dravite is 3.35 whereas that of Bronzite is 3.35.
