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