Omphacite and Esperite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Omphacite and Esperite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Esperite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 4.28-4.42 whereas that of Esperite is 4.28-4.42.
