Agate and Austinite Chemical Formula

While comparing Agate and Austinite 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 Agate and Austinite chemical formula.

  • Chemical formula of Agate- SiO2
  • Chemical formula of Austinite- CaZn(AsO4)(OH)

Agate and Austinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Agate and Austinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Agate and Austinite Optical Properties during the identification of gemstone. Specific gravity of Agate is 4.12 whereas that of Austinite is 4.12.
