Common Opal and Euclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Common Opal and Euclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Common Opal and Euclase Optical Properties during the identification of gemstone. Specific gravity of Common Opal is 3.08-3.12 whereas that of Euclase is 3.08-3.12.
