Muscovite and Emerald Specific Gravity
Another important criteria for qualitative analysis of gemstones is Muscovite and Emerald Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Muscovite and Emerald Optical Properties during the identification of gemstone. Specific gravity of Muscovite is 2.67-2.78 whereas that of Emerald is 2.67-2.78.
