Apophyllite and Chlorapatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Apophyllite and Chlorapatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apophyllite and Chlorapatite Optical Properties during the identification of gemstone. Specific gravity of Apophyllite is 3.17-3.18 whereas that of Chlorapatite is 3.17-3.18.
