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