Periclase and Bustamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Periclase and Bustamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Periclase and Bustamite Optical Properties during the identification of gemstone. Specific gravity of Periclase is 3.32-3.43 whereas that of Bustamite is 3.32-3.43.
