Uvite and Lazulite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Uvite and Lazulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Uvite and Lazulite Optical Properties during the identification of gemstone. Specific gravity of Uvite is 3.04-3.17 whereas that of Lazulite is 3.04-3.17.
