Fuchsite and Spodumene Specific Gravity

Another important criteria for qualitative analysis of gemstones is Fuchsite and Spodumene Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fuchsite and Spodumene Optical Properties during the identification of gemstone. Specific gravity of Fuchsite is 3.15-3.21 whereas that of Spodumene is 3.15-3.21.
