Purpurite and Williamsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Purpurite and Williamsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Purpurite and Williamsite Optical Properties during the identification of gemstone. Specific gravity of Purpurite is 2.51-2.63 whereas that of Williamsite is 2.51-2.63.
