Moroxite and Norbergite Specific Gravity

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