Moissanite and Ajoite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moissanite and Ajoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Ajoite Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 2.96 whereas that of Ajoite is 2.96.
