Achroite and Prase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Achroite and Prase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Achroite Vs Prase during the identification of gemstone. Specific gravity of Achroite is whereas that of Prase is .
