Spodumene and Fibrolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spodumene and Fibrolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spodumene and Fibrolite Optical Properties during the identification of gemstone. Specific gravity of Spodumene is 3.14-3.25 whereas that of Fibrolite is 3.14-3.25.
