Apatite and Musgravite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Apatite and Musgravite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apatite and Musgravite Optical Properties during the identification of gemstone. Specific gravity of Apatite is 3.62-3.68 whereas that of Musgravite is 3.62-3.68.
