While comparing Trinitite and Gibbsite 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 Trinitite and Gibbsite chemical formula.
Another important criteria for qualitative analysis of gemstones is Trinitite and Gibbsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Trinitite and Gibbsite Optical Properties during the identification of gemstone. Specific gravity of Trinitite is 2.35 whereas that of Gibbsite is 2.35.
