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

Cerussite and Grandidierite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cerussite and Grandidierite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cerussite and Grandidierite Optical Properties during the identification of gemstone. Specific gravity of Cerussite is 2.85-3.00 whereas that of Grandidierite is 2.85-3.00.
