Apatite and Beryl Specific Gravity

Another important criteria for qualitative analysis of gemstones is Apatite and Beryl Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apatite and Beryl Optical Properties during the identification of gemstone. Specific gravity of Apatite is 2.60-2.90 whereas that of Beryl is 2.60-2.90.
