Andesine and Atacamite Chemical Formula
While comparing Andesine and Atacamite 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 Andesine and Atacamite chemical formula.
- Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8
- Chemical formula of Atacamite- Cu2Cl(OH)3
Andesine and Atacamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andesine and Atacamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andesine and Atacamite Optical Properties during the identification of gemstone. Specific gravity of Andesine is 3.745-3.776 whereas that of Atacamite is 3.745-3.776.
