Sunstone and Andradite Chemical Formula

While comparing Sunstone and Andradite 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 Sunstone and Andradite chemical formula.

  • Chemical formula of Sunstone- Microcline: KAlSi3O8 Oligoclase: (Na,Ca)Al1-2Si3-2O8
  • Chemical formula of Andradite- Ca 3Fe 2(SiO 4) 3Arthur Thomas , Gemstones (2009)

Sunstone and Andradite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sunstone and Andradite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Andradite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 3.70-4.10 whereas that of Andradite is 3.70-4.10.
