Chrysocolla and Achroite Chemical Formula
While comparing Chrysocolla and Achroite 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 Chrysocolla and Achroite chemical formula.
- Chemical formula of Chrysocolla- Cu2H2Si2O5(OH)4
- Chemical formula of Achroite- Na(Li 1.5Al 1.5)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012) Formula given for elbaite.
Chrysocolla and Achroite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysocolla and Achroite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysocolla and Achroite Optical Properties during the identification of gemstone. Specific gravity of Chrysocolla is 2.90-3.40 whereas that of Achroite is 2.90-3.40.
