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

Dravite and Muscovite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dravite and Muscovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dravite and Muscovite Optical Properties during the identification of gemstone. Specific gravity of Dravite is 2.78-2.88 whereas that of Muscovite is 2.78-2.88.
