Annabergite and Adamite Chemical Formula
While comparing Annabergite and Adamite 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 Annabergite and Adamite chemical formula.
- Chemical formula of Annabergite- Ni3(AsO4)2•8(H2O)
- Chemical formula of Adamite- Zn 2(AsO 4)(OH)Michael OâDonoghue , Gems, Sixth edition (2006)
Annabergite and Adamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Annabergite and Adamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Annabergite and Adamite Optical Properties during the identification of gemstone. Specific gravity of Annabergite is 4.32-4.48 whereas that of Adamite is 4.32-4.48.
