Lazurite and Wavellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lazurite and Wavellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazurite and Wavellite Optical Properties during the identification of gemstone. Specific gravity of Lazurite is 2.36 whereas that of Wavellite is 2.36.
