Goethite and Liddicoatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Goethite and Liddicoatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Goethite and Liddicoatite Optical Properties during the identification of gemstone. Specific gravity of Goethite is 3.02 whereas that of Liddicoatite is 3.02.
