Piemontite and Anatase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Piemontite and Anatase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Piemontite and Anatase Optical Properties during the identification of gemstone. Specific gravity of Piemontite is 3.82-3.97 whereas that of Anatase is 3.82-3.97.
