Muscovite and Danburite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Muscovite and Danburite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Muscovite and Danburite Optical Properties during the identification of gemstone. Specific gravity of Muscovite is 2.97-3.03 whereas that of Danburite is 2.97-3.03.
