While comparing Hemimorphite and Stichtite 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 Hemimorphite and Stichtite chemical formula.
Another important criteria for qualitative analysis of gemstones is Hemimorphite and Stichtite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hemimorphite and Stichtite Optical Properties during the identification of gemstone. Specific gravity of Hemimorphite is 2.11-2.20 whereas that of Stichtite is 2.11-2.20.
