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

Cerussite and Chalcedony Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cerussite and Chalcedony Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cerussite and Chalcedony Optical Properties during the identification of gemstone. Specific gravity of Cerussite is 2.55-2.70 whereas that of Chalcedony is 2.55-2.70.
