Uvite and Chlorastrolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Uvite and Chlorastrolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Uvite and Chlorastrolite Optical Properties during the identification of gemstone. Specific gravity of Uvite is 3.1-3.5 whereas that of Chlorastrolite is 3.1-3.5.
