Jet and Diaspore Specific Gravity

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