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

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