Adamite and Andesine Chemical Formula

While comparing Adamite and Andesine 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 Adamite and Andesine chemical formula.

  • Chemical formula of Adamite- Zn 2(AsO 4)(OH)Michael O’Donoghue , Gems, Sixth edition (2006)
  • Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8

Adamite and Andesine Specific Gravity

Another important criteria for qualitative analysis of gemstones is Adamite and Andesine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Adamite and Andesine Optical Properties during the identification of gemstone. Specific gravity of Adamite is 2.65-2.69 whereas that of Andesine is 2.65-2.69.
