Cassiterite and Scheelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cassiterite and Scheelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cassiterite and Scheelite Optical Properties during the identification of gemstone. Specific gravity of Cassiterite is 5.9-6.3 whereas that of Scheelite is 5.9-6.3.
