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