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