Prase and Unakite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Prase and Unakite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prase and Unakite Optical Properties during the identification of gemstone. Specific gravity of Prase is 2.85-3.20 whereas that of Unakite is 2.85-3.20.
