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

Cerussite and Ettringite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cerussite and Ettringite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cerussite and Ettringite Optical Properties during the identification of gemstone. Specific gravity of Cerussite is 1.77 whereas that of Ettringite is 1.77.
