Euclase and Mottramite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Euclase and Mottramite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Euclase and Mottramite Optical Properties during the identification of gemstone. Specific gravity of Euclase is 5.9 whereas that of Mottramite is 5.9.
