Phosphophyllite and Lazurite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Phosphophyllite and Lazurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosphophyllite and Lazurite Optical Properties during the identification of gemstone. Specific gravity of Phosphophyllite is 2.75 whereas that of Lazurite is 2.75.
