Omphacite and Creedite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Omphacite and Creedite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Creedite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 2.70 whereas that of Creedite is 2.70.
