While comparing Charoite and Malachite 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 Charoite and Malachite chemical formula.
Another important criteria for qualitative analysis of gemstones is Charoite and Malachite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Charoite and Malachite Optical Properties during the identification of gemstone. Specific gravity of Charoite is 3.25-4.10 whereas that of Malachite is 3.25-4.10.
