Apatite and Halite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Apatite and Halite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apatite and Halite Optical Properties during the identification of gemstone. Specific gravity of Apatite is 2.17 whereas that of Halite is 2.17.
