Wernerite and Apatite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Wernerite and Apatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wernerite and Apatite Optical Properties during the identification of gemstone. Specific gravity of Wernerite is 3.16-3.23 whereas that of Apatite is 3.16-3.23.
