Cavansite and Norbergite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cavansite and Norbergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cavansite and Norbergite Optical Properties during the identification of gemstone. Specific gravity of Cavansite is 3.177 whereas that of Norbergite is 3.177.
