Sylvite and Beudantite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sylvite and Beudantite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sylvite and Beudantite Optical Properties during the identification of gemstone. Specific gravity of Sylvite is 4.48 whereas that of Beudantite is 4.48.
