Annabergite and Rhodolite Chemical Formula
While comparing Annabergite and Rhodolite 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 Rhodolite chemical formula.
- Chemical formula of Annabergite- Ni3(AsO4)2•8(H2O)
- Chemical formula of Rhodolite- (Mg,Fe)3Al2Si3O12
Annabergite and Rhodolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Annabergite and Rhodolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Annabergite and Rhodolite Optical Properties during the identification of gemstone. Specific gravity of Annabergite is 3.84 whereas that of Rhodolite is 3.84.
