Gahnite and Phosgenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gahnite and Phosgenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gahnite and Phosgenite Optical Properties during the identification of gemstone. Specific gravity of Gahnite is 6.13 whereas that of Phosgenite is 6.13.
