While comparing Hexagonite and Narsarsukite 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 Hexagonite and Narsarsukite chemical formula.
Another important criteria for qualitative analysis of gemstones is Hexagonite and Narsarsukite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hexagonite and Narsarsukite Optical Properties during the identification of gemstone. Specific gravity of Hexagonite is 2.72-2.83 whereas that of Narsarsukite is 2.72-2.83.
