While comparing Ajoite and Scheelite 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 Ajoite and Scheelite chemical formula.
Another important criteria for qualitative analysis of gemstones is Ajoite and Scheelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ajoite and Scheelite Optical Properties during the identification of gemstone. Specific gravity of Ajoite is 5.9-6.3 whereas that of Scheelite is 5.9-6.3.
