Williamsite and Pyrite Chemical Formula

While comparing Williamsite and Pyrite 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 Williamsite and Pyrite chemical formula.

Williamsite and Pyrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Williamsite and Pyrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Williamsite Vs Pyrite during the identification of gemstone. Specific gravity of Williamsite is whereas that of Pyrite is .
