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

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