Jacobsite and Orthoclase Specific Gravity

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