Diaspore and Siderite Specific Gravity

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