While comparing Tinaksite and Dallasite 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 Tinaksite and Dallasite chemical formula.
Another important criteria for qualitative analysis of gemstones is Tinaksite and Dallasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tinaksite and Dallasite Optical Properties during the identification of gemstone. Specific gravity of Tinaksite is 2.58-2.91 whereas that of Dallasite is 2.58-2.91.
