Annabergite and Fuchsite Chemical Formula
While comparing Annabergite and Fuchsite 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 Fuchsite chemical formula.
- Chemical formula of Annabergite- Ni3(AsO4)2•8(H2O)
- Chemical formula of Fuchsite- K(Al,Cr) 3Si 3O 10(OH) 2Gemdat.org , Management Team (2012)
Annabergite and Fuchsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Annabergite and Fuchsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Annabergite and Fuchsite Optical Properties during the identification of gemstone. Specific gravity of Annabergite is 2.77-2.88 whereas that of Fuchsite is 2.77-2.88.
