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