Rhodizite and Siderite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rhodizite and Siderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodizite and Siderite Optical Properties during the identification of gemstone. Specific gravity of Rhodizite is 3.83-3.89 whereas that of Siderite is 3.83-3.89.
