Rhodochrosite and Prehnite Chemical Formula

While comparing Rhodochrosite and Prehnite 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 Rhodochrosite and Prehnite chemical formula.

  • Chemical formula of Rhodochrosite- MnCO3
  • Chemical formula of Prehnite- Ca2Al2Si3O12(OH)

Rhodochrosite and Prehnite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rhodochrosite and Prehnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodochrosite and Prehnite Optical Properties during the identification of gemstone. Specific gravity of Rhodochrosite is 2.80-2.95 whereas that of Prehnite is 2.80-2.95.
