Cryolite and Cerussite Chemical Formula

While comparing Cryolite and Cerussite 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 Cerussite chemical formula.

Cryolite and Cerussite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cryolite and Cerussite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Cerussite Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 6.46-6.57 whereas that of Cerussite is 6.46-6.57.
