Moissanite and Poudretteite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moissanite and Poudretteite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Poudretteite Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 2.51-2.53 whereas that of Poudretteite is 2.51-2.53.
