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