Creedite and Siderite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Creedite and Siderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Creedite and Siderite Optical Properties during the identification of gemstone. Specific gravity of Creedite is 3.83-3.89 whereas that of Siderite is 3.83-3.89.
