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

Fuchsite and Hercynite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fuchsite and Hercynite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fuchsite and Hercynite Optical Properties during the identification of gemstone. Specific gravity of Fuchsite is 4.39 whereas that of Hercynite is 4.39.
