Apatite and Chabazite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Apatite and Chabazite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apatite and Chabazite Optical Properties during the identification of gemstone. Specific gravity of Apatite is 2.08-2.16 whereas that of Chabazite is 2.08-2.16.
