Moissanite and Wulfenite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moissanite and Wulfenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Wulfenite Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 6.50-7.00 whereas that of Wulfenite is 6.50-7.00.
