Almandine and Anglesite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Almandine and Anglesite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Almandine and Anglesite Optical Properties during the identification of gemstone. Specific gravity of Almandine is 6.30-6.39 whereas that of Anglesite is 6.30-6.39.
