Euclase and Sillimanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Euclase and Sillimanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Euclase and Sillimanite Optical Properties during the identification of gemstone. Specific gravity of Euclase is 3.20-3.26 whereas that of Sillimanite is 3.20-3.26.
