Pollucite and Uvite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pollucite and Uvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pollucite Vs Uvite during the identification of gemstone. Specific gravity of Pollucite is whereas that of Uvite is .
