Cassiterite and Cryolite Chemical Formula

While comparing Cassiterite 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 Cassiterite and Cryolite chemical formula.

Cassiterite and Cryolite Specific Gravity

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