Fuchsite and Umbalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fuchsite and Umbalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fuchsite and Umbalite Optical Properties during the identification of gemstone. Specific gravity of Fuchsite is 3.62-4.33 whereas that of Umbalite is 3.62-4.33.
