Cerussite and Calcite Chemical Formula

While comparing Cerussite and Calcite 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 Calcite chemical formula.

Cerussite and Calcite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cerussite and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cerussite and Calcite Optical Properties during the identification of gemstone. Specific gravity of Cerussite is 2.67-2.73 whereas that of Calcite is 2.67-2.73.
