Fuchsite and Austinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Fuchsite and Austinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fuchsite and Austinite Optical Properties during the identification of gemstone. Specific gravity of Fuchsite is 4.12 whereas that of Austinite is 4.12.
