Hercynite and Hematite Chemical Formula
While comparing Hercynite 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 Hercynite and Hematite chemical formula.

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