Seraphinite and Andesine Specific Gravity

Another important criteria for qualitative analysis of gemstones is Seraphinite and Andesine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Seraphinite and Andesine Optical Properties during the identification of gemstone. Specific gravity of Seraphinite is 2.65-2.69 whereas that of Andesine is 2.65-2.69.
