Annabergite and Linarite Chemical Formula
While comparing Annabergite and Linarite 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 Linarite chemical formula.
- Chemical formula of Annabergite- Ni3(AsO4)2•8(H2O)
- Chemical formula of Linarite- PbCu(SO 4)(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006)
Annabergite and Linarite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Annabergite and Linarite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Annabergite and Linarite Optical Properties during the identification of gemstone. Specific gravity of Annabergite is 5.35 whereas that of Linarite is 5.35.
