Rossmanite and Jasper Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rossmanite and Jasper Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rossmanite and Jasper Optical Properties during the identification of gemstone. Specific gravity of Rossmanite is 2.58-2.91 whereas that of Jasper is 2.58-2.91.
