Fluorapatite and Norbergite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fluorapatite and Norbergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fluorapatite and Norbergite Optical Properties during the identification of gemstone. Specific gravity of Fluorapatite is 3.177 whereas that of Norbergite is 3.177.
