Phosgenite and Iolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Phosgenite and Iolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosgenite and Iolite Optical Properties during the identification of gemstone. Specific gravity of Phosgenite is 2.6-2.7 whereas that of Iolite is 2.6-2.7.
