Moissanite and Turquoise Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moissanite and Turquoise Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moissanite and Turquoise Optical Properties during the identification of gemstone. Specific gravity of Moissanite is 2.30-2.90 whereas that of Turquoise is 2.30-2.90.
