Gaylussite and Marialite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gaylussite and Marialite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gaylussite and Marialite Optical Properties during the identification of gemstone. Specific gravity of Gaylussite is 2.50 whereas that of Marialite is 2.50.
