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