Omphacite and Stichtite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Omphacite and Stichtite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Stichtite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 2.11-2.20 whereas that of Stichtite is 2.11-2.20.
