Cassiterite and Childrenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cassiterite and Childrenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cassiterite and Childrenite Optical Properties during the identification of gemstone. Specific gravity of Cassiterite is 3.06-3.25 whereas that of Childrenite is 3.06-3.25.
