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

Dravite and Quartz Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dravite and Quartz Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dravite and Quartz Optical Properties during the identification of gemstone. Specific gravity of Dravite is 2.65 whereas that of Quartz is 2.65.
