While comparing Eosphorite and Hypersthene 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 Eosphorite and Hypersthene chemical formula.
Another important criteria for qualitative analysis of gemstones is Eosphorite and Hypersthene Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Eosphorite and Hypersthene Optical Properties during the identification of gemstone. Specific gravity of Eosphorite is 3.45-3.55 whereas that of Hypersthene is 3.45-3.55.
