Fluorapatite and Schorl Specific Gravity

Another important criteria for qualitative analysis of gemstones is Fluorapatite and Schorl Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fluorapatite and Schorl Optical Properties during the identification of gemstone. Specific gravity of Fluorapatite is 3.18-3.22 whereas that of Schorl is 3.18-3.22.
