Neptunite and Kunzite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Neptunite and Kunzite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Neptunite and Kunzite Optical Properties during the identification of gemstone. Specific gravity of Neptunite is 3.15-3.21 whereas that of Kunzite is 3.15-3.21.
