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

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