Ceylonite and Common Opal Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ceylonite and Common Opal Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ceylonite and Common Opal Optical Properties during the identification of gemstone. Specific gravity of Ceylonite is 1.98-2.50 whereas that of Common Opal is 1.98-2.50.
