Fuchsite and Erythrite Chemical Formula
While comparing Fuchsite and Erythrite 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 Erythrite chemical formula.
- Chemical formula of Fuchsite- K(Al,Cr) 3Si 3O 10(OH) 2Gemdat.org , Management Team (2012)
- Chemical formula of Erythrite- Co3(AsO4)2•8(H2O)
Fuchsite and Erythrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fuchsite and Erythrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fuchsite and Erythrite Optical Properties during the identification of gemstone. Specific gravity of Fuchsite is 3.06 whereas that of Erythrite is 3.06.
