Rhodolite and Jacobsite Chemical Formula

While comparing Rhodolite 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 Rhodolite and Jacobsite chemical formula.

  • Chemical formula of Rhodolite- (Mg,Fe)3Al2Si3O12
  • Chemical formula of Jacobsite- (Mn2+ ,Fe2+ ,Mg)(Fe3+ ,Mn3+ ) 2O 4Anthony et al , Handbook of mineralogy (2001)

Rhodolite and Jacobsite Specific Gravity

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