Cavansite and Jacobsite Specific Gravity

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