Rossmanite and Fibrolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rossmanite and Fibrolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rossmanite and Fibrolite Optical Properties during the identification of gemstone. Specific gravity of Rossmanite is 3.14-3.25 whereas that of Fibrolite is 3.14-3.25.
