Omphacite and Simpsonite Specific Gravity

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