While comparing Ajoite and Shigaite 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 Shigaite chemical formula.
Another important criteria for qualitative analysis of gemstones is Ajoite and Shigaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ajoite and Shigaite Optical Properties during the identification of gemstone. Specific gravity of Ajoite is 2.32 whereas that of Shigaite is 2.32.
