Phosgenite and Tanzanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Phosgenite and Tanzanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosgenite and Tanzanite Optical Properties during the identification of gemstone. Specific gravity of Phosgenite is 3.35 whereas that of Tanzanite is 3.35.
