Mimetite and Gaspeite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Mimetite and Gaspeite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Mimetite and Gaspeite Optical Properties during the identification of gemstone. Specific gravity of Mimetite is 3.71 whereas that of Gaspeite is 3.71.
