Euclase and Almandine Specific Gravity

Another important criteria for qualitative analysis of gemstones is Euclase and Almandine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Euclase and Almandine Optical Properties during the identification of gemstone. Specific gravity of Euclase is 3.95-4.30 whereas that of Almandine is 3.95-4.30.
