Common Opal and Enstatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Common Opal and Enstatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Common Opal and Enstatite Optical Properties during the identification of gemstone. Specific gravity of Common Opal is 3.20-3.25 whereas that of Enstatite is 3.20-3.25.
