Euclase and Opal Specific Gravity
Another important criteria for qualitative analysis of gemstones is Euclase and Opal Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Euclase and Opal Optical Properties during the identification of gemstone. Specific gravity of Euclase is 1.98-2.25 whereas that of Opal is 1.98-2.25.
