Apatite and Iddingsite Specific Gravity

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