Seraphinite and Topaz Specific Gravity

Another important criteria for qualitative analysis of gemstones is Seraphinite and Topaz Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Seraphinite and Topaz Optical Properties during the identification of gemstone. Specific gravity of Seraphinite is 3.49-3.57 whereas that of Topaz is 3.49-3.57.
