Cassiterite and Phenakite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cassiterite and Phenakite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cassiterite and Phenakite Optical Properties during the identification of gemstone. Specific gravity of Cassiterite is 2.90-2.98 whereas that of Phenakite is 2.90-2.98.
