Almandine and Sunstone Chemical Formula

While comparing Almandine and Sunstone 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 Almandine and Sunstone chemical formula.

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

Almandine and Sunstone Specific Gravity

Another important criteria for qualitative analysis of gemstones is Almandine and Sunstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Almandine and Sunstone Optical Properties during the identification of gemstone. Specific gravity of Almandine is 2.62-2.65 whereas that of Sunstone is 2.62-2.65.
