Uvite and Pyrite Chemical Formula

While comparing Uvite 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 Uvite and Pyrite chemical formula.

Uvite and Pyrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Uvite and Pyrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Uvite and Pyrite Optical Properties during the identification of gemstone. Specific gravity of Uvite is 5.00-5.20 whereas that of Pyrite is 5.00-5.20.
