Moissanite and Black Opal Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moissanite and Black Opal Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Black Opal Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 1.97-2.22 whereas that of Black Opal is 1.97-2.22.
