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

Cassiterite and Pargasite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cassiterite and Pargasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cassiterite and Pargasite Optical Properties during the identification of gemstone. Specific gravity of Cassiterite is 3.04-3.26 whereas that of Pargasite is 3.04-3.26.
