Omphacite and Pietersite Specific Gravity

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