Hercynite and Pietersite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hercynite and Pietersite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hercynite and Pietersite Optical Properties during the identification of gemstone. Specific gravity of Hercynite is Not Available whereas that of Pietersite is Not Available.
