Melanite and Fluorapatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Melanite and Fluorapatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Melanite and Fluorapatite Optical Properties during the identification of gemstone. Specific gravity of Melanite is 3.1-3.25 whereas that of Fluorapatite is 3.1-3.25.
