Humite and Fuchsite Physical Properties

Humite and Fuchsite Chemical Formula

While comparing Humite 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 Humite and Fuchsite chemical formula.

• Chemical formula of Humite- (Mg,Fe2+ ) 7(SiO 4) 3(F,OH) 2Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Fuchsite- K(Al,Cr) 3Si 3O 10(OH) 2Gemdat.org , Management Team (2012)

Humite and Fuchsite Specific Gravity

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