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

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