Andesine and Apatite Specific Gravity

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