While comparing Tanzanite and Pallasite 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 Tanzanite and Pallasite chemical formula.
Another important criteria for qualitative analysis of gemstones is Tanzanite and Pallasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Pallasite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is Not Available whereas that of Pallasite is Not Available.
