Jacobsite and Goshenite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Jacobsite and Goshenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jacobsite and Goshenite Optical Properties during the identification of gemstone. Specific gravity of Jacobsite is 2.60-2.90 whereas that of Goshenite is 2.60-2.90.
