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

Cassiterite and Williamsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cassiterite and Williamsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cassiterite and Williamsite Optical Properties during the identification of gemstone. Specific gravity of Cassiterite is 2.51-2.63 whereas that of Williamsite is 2.51-2.63.
