While comparing Hercynite and Scorodite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Hercynite and Scorodite chemical formula.
Another important criteria for qualitative analysis of gemstones is Hercynite and Scorodite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hercynite and Scorodite Optical Properties during the identification of gemstone. Specific gravity of Hercynite is Not Available whereas that of Scorodite is Not Available.
