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