Wernerite and Rubellite Chemical Formula
While comparing Wernerite and Rubellite 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 Wernerite and Rubellite chemical formula.

Wernerite and Rubellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Wernerite and Rubellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wernerite and Rubellite Optical Properties during the identification of gemstone. Specific gravity of Wernerite is 3.01-3.06 whereas that of Rubellite is 3.01-3.06.
