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

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