Omphacite and Villiaumite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Omphacite and Villiaumite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Villiaumite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 2.79 whereas that of Villiaumite is 2.79.
