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