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

Hercynite and Mimetite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hercynite and Mimetite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hercynite and Mimetite Optical Properties during the identification of gemstone. Specific gravity of Hercynite is 7.10 whereas that of Mimetite is 7.10.
