Sphalerite and Thomsonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sphalerite and Thomsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sphalerite and Thomsonite Optical Properties during the identification of gemstone. Specific gravity of Sphalerite is 2.25-2.40 whereas that of Thomsonite is 2.25-2.40.
