Cassiterite and Atacamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cassiterite and Atacamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cassiterite and Atacamite Optical Properties during the identification of gemstone. Specific gravity of Cassiterite is 3.745-3.776 whereas that of Atacamite is 3.745-3.776.
