Cassiterite and Viridine Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cassiterite and Viridine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cassiterite and Viridine Optical Properties during the identification of gemstone. Specific gravity of Cassiterite is 3.05-3.21 whereas that of Viridine is 3.05-3.21.
