Uvarovite and Prehnite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Uvarovite and Prehnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Uvarovite and Prehnite Optical Properties during the identification of gemstone. Specific gravity of Uvarovite is 2.80-2.95 whereas that of Prehnite is 2.80-2.95.
