Tantalite and Phosphosiderite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tantalite and Phosphosiderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tantalite and Phosphosiderite Optical Properties during the identification of gemstone. Specific gravity of Tantalite is 2.74-2.76 whereas that of Phosphosiderite is 2.74-2.76.
