Cassiterite and Amethyst Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cassiterite and Amethyst Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cassiterite and Amethyst Optical Properties during the identification of gemstone. Specific gravity of Cassiterite is 2.65 whereas that of Amethyst is 2.65.
