Simpsonite and Feldspar Specific Gravity
Another important criteria for qualitative analysis of gemstones is Simpsonite and Feldspar Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Simpsonite and Feldspar Optical Properties during the identification of gemstone. Specific gravity of Simpsonite is 2.56-2.75 whereas that of Feldspar is 2.56-2.75.
