Augite and Sphalerite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Augite and Sphalerite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Augite and Sphalerite Optical Properties during the identification of gemstone. Specific gravity of Augite is 3.95-4.10 whereas that of Sphalerite is 3.95-4.10.
