While comparing Scorzalite and Pyromorphite 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 Scorzalite and Pyromorphite chemical formula.
Another important criteria for qualitative analysis of gemstones is Scorzalite and Pyromorphite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Scorzalite and Pyromorphite Optical Properties during the identification of gemstone. Specific gravity of Scorzalite is 6.5-7.1 whereas that of Pyromorphite is 6.5-7.1.
