Phosphosiderite and Hematite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Phosphosiderite and Hematite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosphosiderite and Hematite Optical Properties during the identification of gemstone. Specific gravity of Phosphosiderite is 5.00-5.30 whereas that of Hematite is 5.00-5.30.
