Enstatite and Lazurite Specific Gravity

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