Dravite and Dravite Chemical Formula

While comparing Dravite 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 Dravite and Dravite chemical formula.

Dravite and Dravite Specific Gravity

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