Euclase and Charlesite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Euclase and Charlesite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Euclase and Charlesite Optical Properties during the identification of gemstone. Specific gravity of Euclase is 1.79 whereas that of Charlesite is 1.79.
