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