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