Andesine and Jacobsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Andesine and Jacobsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andesine and Jacobsite Optical Properties during the identification of gemstone. Specific gravity of Andesine is 4.76-5.03 whereas that of Jacobsite is 4.76-5.03.
