Apatite and Chiastolite Specific Gravity

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