Phosgenite and Hibonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Phosgenite and Hibonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosgenite and Hibonite Optical Properties during the identification of gemstone. Specific gravity of Phosgenite is 3.84 whereas that of Hibonite is 3.84.
