Neptunite and Pyrite Chemical Formula

While comparing Neptunite 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 Neptunite and Pyrite chemical formula.

Neptunite and Pyrite Specific Gravity

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