Goethite and Idocrase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Goethite and Idocrase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Goethite and Idocrase Optical Properties during the identification of gemstone. Specific gravity of Goethite is Not Available whereas that of Idocrase is Not Available.
