Foitite and Fuchsite Physical Properties

Foitite and Fuchsite Chemical Formula

While comparing Foitite and Fuchsite 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 Foitite and Fuchsite chemical formula.

• Chemical formula of Foitite- Na x[Fe2+2(Al,Fe3+ )]Al 6(BO 3) 3Si 6O 18(OH) 4Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Fuchsite- K(Al,Cr) 3Si 3O 10(OH) 2Gemdat.org , Management Team (2012)

Foitite and Fuchsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Foitite and Fuchsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Foitite and Fuchsite Optical Properties during the identification of gemstone. Specific gravity of Foitite is 2.77-2.88 whereas that of Fuchsite is 2.77-2.88.
