While comparing Jadeite and Hiddenite 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 Jadeite and Hiddenite chemical formula.
Another important criteria for qualitative analysis of gemstones is Jadeite and Hiddenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jadeite and Hiddenite Optical Properties during the identification of gemstone. Specific gravity of Jadeite is 3.15-3.21 whereas that of Hiddenite is 3.15-3.21.
