Grossular and Pyrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Grossular and Pyrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Grossular and Pyrite Optical Properties during the identification of gemstone. Specific gravity of Grossular is 5.00-5.20 whereas that of Pyrite is 5.00-5.20.
