Fibrolite and Erythrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fibrolite and Erythrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fibrolite and Erythrite Optical Properties during the identification of gemstone. Specific gravity of Fibrolite is 3.06 whereas that of Erythrite is 3.06.
