Pumpellyite and Mimetite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pumpellyite and Mimetite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pumpellyite and Mimetite Optical Properties during the identification of gemstone. Specific gravity of Pumpellyite is 7.10 whereas that of Mimetite is 7.10.
