Uvarovite and Purpurite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Uvarovite and Purpurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Uvarovite and Purpurite Optical Properties during the identification of gemstone. Specific gravity of Uvarovite is 3.2-3.4 whereas that of Purpurite is 3.2-3.4.
