Annabergite and Carnelian Chemical Formula
While comparing Annabergite and Carnelian 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 Carnelian chemical formula.
- Chemical formula of Annabergite- Ni3(AsO4)2•8(H2O)
- Chemical formula of Carnelian- SiO2
Annabergite and Carnelian Specific Gravity
Another important criteria for qualitative analysis of gemstones is Annabergite and Carnelian Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Annabergite and Carnelian Optical Properties during the identification of gemstone. Specific gravity of Annabergite is 2.58-2.64 whereas that of Carnelian is 2.58-2.64.
