Andradite and Simpsonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andradite and Simpsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andradite and Simpsonite Optical Properties during the identification of gemstone. Specific gravity of Andradite is Not Available whereas that of Simpsonite is Not Available.
