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

Cassiterite and Iolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cassiterite and Iolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cassiterite and Iolite Optical Properties during the identification of gemstone. Specific gravity of Cassiterite is 2.6-2.7 whereas that of Iolite is 2.6-2.7.
