Omphacite and Witherite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Omphacite and Witherite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Witherite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 4.27-4.35 whereas that of Witherite is 4.27-4.35.
