Apophyllite and Cassiterite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Apophyllite and Cassiterite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apophyllite and Cassiterite Optical Properties during the identification of gemstone. Specific gravity of Apophyllite is 6.86-7.03 whereas that of Cassiterite is 6.86-7.03.
