While comparing Iddingsite and Scorzalite 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 Iddingsite and Scorzalite chemical formula.
Another important criteria for qualitative analysis of gemstones is Iddingsite and Scorzalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Iddingsite and Scorzalite Optical Properties during the identification of gemstone. Specific gravity of Iddingsite is 3.31 whereas that of Scorzalite is 3.31.
