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