Cryolite and Rubellite Chemical Formula

While comparing Cryolite 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 Cryolite and Rubellite chemical formula.

Cryolite and Rubellite Specific Gravity

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