While comparing Childrenite and Musgravite 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 Childrenite and Musgravite chemical formula.
Another important criteria for qualitative analysis of gemstones is Childrenite and Musgravite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Childrenite and Musgravite Optical Properties during the identification of gemstone. Specific gravity of Childrenite is 3.62-3.68 whereas that of Musgravite is 3.62-3.68.
