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