- Chemical formula of Muscovite- KAl 2AlSi 3O 10(OH) 2Walter Schumann , Gemstones of the world (2001) More from other references
Emerald and Muscovite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Emerald and Muscovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Emerald and Muscovite Optical Properties during the identification of gemstone. Specific gravity of Emerald is 2.78-2.88 whereas that of Muscovite is 2.78-2.88.
