Gahnite and Moissanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gahnite and Moissanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gahnite and Moissanite Optical Properties during the identification of gemstone. Specific gravity of Gahnite is 3.17-3.24 whereas that of Moissanite is 3.17-3.24.
