While comparing Prismatine and Hexagonite 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 Prismatine and Hexagonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Prismatine and Hexagonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prismatine and Hexagonite Optical Properties during the identification of gemstone. Specific gravity of Prismatine is 2.98-3.03 whereas that of Hexagonite is 2.98-3.03.
