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