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