While comparing Hiddenite and Stolzite 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 Hiddenite and Stolzite chemical formula.
Another important criteria for qualitative analysis of gemstones is Hiddenite and Stolzite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hiddenite and Stolzite Optical Properties during the identification of gemstone. Specific gravity of Hiddenite is 2 whereas that of Stolzite is 2.
