Powellite and Fire Agate Specific Gravity
Another important criteria for qualitative analysis of gemstones is Powellite and Fire Agate Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Powellite and Fire Agate Optical Properties during the identification of gemstone. Specific gravity of Powellite is 2.60-2.64 whereas that of Fire Agate is 2.60-2.64.
