Omphacite and Rock Crystal Specific Gravity
Another important criteria for qualitative analysis of gemstones is Omphacite and Rock Crystal Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Rock Crystal Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 2.65 whereas that of Rock Crystal is 2.65.
