While comparing Musgravite and Zincite 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 Musgravite and Zincite chemical formula.
Another important criteria for qualitative analysis of gemstones is Musgravite and Zincite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Musgravite and Zincite Optical Properties during the identification of gemstone. Specific gravity of Musgravite is 5.50-5.90 whereas that of Zincite is 5.50-5.90.
