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