While comparing Elaeolite and Atacamite 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 Elaeolite and Atacamite chemical formula.
Another important criteria for qualitative analysis of gemstones is Elaeolite and Atacamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Elaeolite and Atacamite Optical Properties during the identification of gemstone. Specific gravity of Elaeolite is 3.745-3.776 whereas that of Atacamite is 3.745-3.776.
