Cassiterite and Magnetite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cassiterite and Magnetite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cassiterite and Magnetite Optical Properties during the identification of gemstone. Specific gravity of Cassiterite is 5.2 whereas that of Magnetite is 5.2.
