Cerussite and Uvite Chemical Formula

While comparing Cerussite and Uvite 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 Uvite chemical formula.

Cerussite and Uvite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cerussite and Uvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cerussite and Uvite Optical Properties during the identification of gemstone. Specific gravity of Cerussite is 2.97-3.14 whereas that of Uvite is 2.97-3.14.
