Phosphosiderite and Rossmanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Phosphosiderite and Rossmanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosphosiderite and Rossmanite Optical Properties during the identification of gemstone. Specific gravity of Phosphosiderite is 3 whereas that of Rossmanite is 3.
