Variscite and Siderite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Variscite and Siderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Variscite Vs Siderite during the identification of gemstone. Specific gravity of Variscite is whereas that of Siderite is .
