While comparing Malachite and Leucophanite 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 Malachite and Leucophanite chemical formula.
Another important criteria for qualitative analysis of gemstones is Malachite and Leucophanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Malachite and Leucophanite Optical Properties during the identification of gemstone. Specific gravity of Malachite is Not Available whereas that of Leucophanite is Not Available.
