Pyrite and Hematite Chemical Formula

While comparing Pyrite and Hematite 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 Pyrite and Hematite chemical formula.

Pyrite and Hematite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrite and Hematite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrite and Hematite Optical Properties during the identification of gemstone. Specific gravity of Pyrite is 5.00-5.30 whereas that of Hematite is 5.00-5.30.
