Fluorapatite and Orthoclase Specific Gravity

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