Goethite and Bornite Physical Properties

Goethite and Bornite Chemical Formula

While comparing Goethite and Bornite 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 Bornite chemical formula.

• Chemical formula of Goethite- FeO(OH)Arthur Thomas , Gemstones (2009)
• Chemical formula of Bornite- Cu5FeS4

Goethite and Bornite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Goethite and Bornite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Goethite and Bornite Optical Properties during the identification of gemstone. Specific gravity of Goethite is 5.06-5.08 whereas that of Bornite is 5.06-5.08.
