While comparing Bloodstone and Papagoite 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 Bloodstone and Papagoite chemical formula.
Another important criteria for qualitative analysis of gemstones is Bloodstone and Papagoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bloodstone and Papagoite Optical Properties during the identification of gemstone. Specific gravity of Bloodstone is 3.25 whereas that of Papagoite is 3.25.
