Uvite and Poldervaartite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Uvite and Poldervaartite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Uvite and Poldervaartite Optical Properties during the identification of gemstone. Specific gravity of Uvite is 2.91 whereas that of Poldervaartite is 2.91.
