Seraphinite and Sylvite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Seraphinite and Sylvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Seraphinite and Sylvite Optical Properties during the identification of gemstone. Specific gravity of Seraphinite is 1.993 whereas that of Sylvite is 1.993.
