Verdelite and Sonolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Verdelite and Sonolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Verdelite and Sonolite Optical Properties during the identification of gemstone. Specific gravity of Verdelite is 3.82-4.00 whereas that of Sonolite is 3.82-4.00.
