Forsterite and Sphalerite Specific Gravity

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