Rhodolite and Goethite Physical Properties

Rhodolite and Goethite Chemical Formula

While comparing Rhodolite and Goethite 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 Rhodolite and Goethite chemical formula.

• Chemical formula of Rhodolite- (Mg,Fe)₃Al₂Si₃O₁₂
• Chemical formula of Goethite- FeO(OH)Arthur Thomas , Gemstones (2009)

Rhodolite and Goethite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rhodolite and Goethite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Goethite Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is 4.27-4.29 whereas that of Goethite is 4.27-4.29.
