Moissanite and Labradorite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moissanite and Labradorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Labradorite Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 2.69-2.72 whereas that of Labradorite is 2.69-2.72.
