While comparing Hauyne and Peridot 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 Hauyne and Peridot chemical formula.
Another important criteria for qualitative analysis of gemstones is Hauyne and Peridot Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hauyne and Peridot Optical Properties during the identification of gemstone. Specific gravity of Hauyne is 1.54-1.55 whereas that of Peridot is 1.54-1.55.
