While comparing Star Ruby and Vesuvianite 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 Star Ruby and Vesuvianite chemical formula.
Another important criteria for qualitative analysis of gemstones is Star Ruby and Vesuvianite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Star Ruby and Vesuvianite Optical Properties during the identification of gemstone. Specific gravity of Star Ruby is 3.32-3.43 whereas that of Vesuvianite is 3.32-3.43.
