Phosgenite and Natrolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Phosgenite and Natrolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosgenite and Natrolite Optical Properties during the identification of gemstone. Specific gravity of Phosgenite is 2.20-2.26 whereas that of Natrolite is 2.20-2.26.
