Omphacite and Apophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Omphacite and Apophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Apophyllite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 2.30-2.50 whereas that of Apophyllite is 2.30-2.50.
