While comparing Trinitite and Gaylussite 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 Gaylussite chemical formula.
Another important criteria for qualitative analysis of gemstones is Trinitite and Gaylussite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Trinitite and Gaylussite Optical Properties during the identification of gemstone. Specific gravity of Trinitite is 1.93-1.99 whereas that of Gaylussite is 1.93-1.99.
