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

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