Fluorapatite and Gedrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fluorapatite and Gedrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fluorapatite and Gedrite Optical Properties during the identification of gemstone. Specific gravity of Fluorapatite is 3.15-3.259 whereas that of Gedrite is 3.15-3.259.
