Agate and Turquoise Chemical Formula
While comparing Agate and Turquoise 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 Agate and Turquoise chemical formula.
- Chemical formula of Agate- SiO2
- Chemical formula of Turquoise- CuAl6(PO4)4(OH)8 • 4H2O
Agate and Turquoise Specific Gravity
Another important criteria for qualitative analysis of gemstones is Agate and Turquoise Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Agate and Turquoise Optical Properties during the identification of gemstone. Specific gravity of Agate is 2.30-2.90 whereas that of Turquoise is 2.30-2.90.
