Cerussite and Ajoite Chemical Formula
While comparing Cerussite and Ajoite 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 Cerussite and Ajoite chemical formula.

Cerussite and Ajoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cerussite and Ajoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cerussite and Ajoite Optical Properties during the identification of gemstone. Specific gravity of Cerussite is 2.96 whereas that of Ajoite is 2.96.
