Chrysoprase and Jet Specific Gravity

Another important criteria for qualitative analysis of gemstones is Chrysoprase and Jet Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Jet Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 1.19-1.35 whereas that of Jet is 1.19-1.35.
