Morion and Goethite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Morion and Goethite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Morion and Goethite Optical Properties during the identification of gemstone. Specific gravity of Morion is 4.27-4.29 whereas that of Goethite is 4.27-4.29.
