Charoite and Cryolite Chemical Formula
While comparing Charoite and Cryolite 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 Charoite and Cryolite chemical formula.

Charoite and Cryolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Charoite and Cryolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Charoite and Cryolite Optical Properties during the identification of gemstone. Specific gravity of Charoite is 2.97 whereas that of Cryolite is 2.97.
