Purpurite and Chrysoprase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Purpurite and Chrysoprase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Purpurite and Chrysoprase Optical Properties during the identification of gemstone. Specific gravity of Purpurite is 2.58-2.64 whereas that of Chrysoprase is 2.58-2.64.
