Apophyllite and Inderite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Apophyllite and Inderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apophyllite and Inderite Optical Properties during the identification of gemstone. Specific gravity of Apophyllite is 1.79 whereas that of Inderite is 1.79.
