Purpurite and Prasiolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Purpurite and Prasiolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Purpurite and Prasiolite Optical Properties during the identification of gemstone. Specific gravity of Purpurite is 2.65 whereas that of Prasiolite is 2.65.
