Fuchsite and Norbergite Physical Properties

Fuchsite and Norbergite Chemical Formula

While comparing Fuchsite and Norbergite 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 Norbergite chemical formula.

• Chemical formula of Fuchsite- K(Al,Cr) 3Si 3O 10(OH) 2Gemdat.org , Management Team (2012)
• Chemical formula of Norbergite- Mg 3(SiO 4)(F,OH) 2Anthony et al , Handbook of Mineralogy (2001)

Fuchsite and Norbergite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Fuchsite and Norbergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fuchsite and Norbergite Optical Properties during the identification of gemstone. Specific gravity of Fuchsite is 3.177 whereas that of Norbergite is 3.177.
