Lazulite and Moss Opal Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lazulite and Moss Opal Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazulite and Moss Opal Optical Properties during the identification of gemstone. Specific gravity of Lazulite is 1.98-2.50 whereas that of Moss Opal is 1.98-2.50.
