Phosphosiderite and Montebrasite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Phosphosiderite and Montebrasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosphosiderite and Montebrasite Optical Properties during the identification of gemstone. Specific gravity of Phosphosiderite is 2.98-3.10 whereas that of Montebrasite is 2.98-3.10.
