While comparing Ajoite and Orthoclase 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 Orthoclase chemical formula.
Another important criteria for qualitative analysis of gemstones is Ajoite and Orthoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ajoite and Orthoclase Optical Properties during the identification of gemstone. Specific gravity of Ajoite is 2.54-2.61 whereas that of Orthoclase is 2.54-2.61.
