Goethite and Jacobsite Physical Properties

Goethite and Jacobsite Chemical Formula

While comparing Goethite and Jacobsite 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 Goethite and Jacobsite chemical formula.

• Chemical formula of Goethite- FeO(OH)Arthur Thomas , Gemstones (2009)
• Chemical formula of Jacobsite- (Mn2+ ,Fe2+ ,Mg)(Fe3+ ,Mn3+ ) 2O 4Anthony et al , Handbook of mineralogy (2001)

Goethite and Jacobsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Goethite and Jacobsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Goethite and Jacobsite Optical Properties during the identification of gemstone. Specific gravity of Goethite is 4.76-5.03 whereas that of Jacobsite is 4.76-5.03.
