Mimetite and Humite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Mimetite and Humite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Mimetite and Humite Optical Properties during the identification of gemstone. Specific gravity of Mimetite is 3.20-3.32 whereas that of Humite is 3.20-3.32.
