While comparing Vanadinite and Anatase 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 Vanadinite and Anatase chemical formula.
Another important criteria for qualitative analysis of gemstones is Vanadinite and Anatase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Vanadinite and Anatase Optical Properties during the identification of gemstone. Specific gravity of Vanadinite is 3.82-3.97 whereas that of Anatase is 3.82-3.97.
