Cordierite and Cassiterite Chemical Formula
While comparing Cordierite and Cassiterite 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 Cordierite and Cassiterite chemical formula.

Cordierite and Cassiterite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cordierite and Cassiterite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cordierite and Cassiterite Optical Properties during the identification of gemstone. Specific gravity of Cordierite is 6.86-7.03 whereas that of Cassiterite is 6.86-7.03.
