Prehnite and Moonstone Chemical Formula

While comparing Prehnite and Moonstone 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 Prehnite and Moonstone chemical formula.

  • Chemical formula of Prehnite- Ca2Al2Si3O12(OH)
  • Chemical formula of Moonstone- Plagioclase Feldspar s: (Na,Ca)Al1-2Si3-2O8 Orthoclase Feldspar : KAlSi3O8

Prehnite and Moonstone Specific Gravity

Another important criteria for qualitative analysis of gemstones is Prehnite and Moonstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prehnite and Moonstone Optical Properties during the identification of gemstone. Specific gravity of Prehnite is 2.56-2.60 whereas that of Moonstone is 2.56-2.60.
