Piemontite and Agate Physical Properties

Piemontite and Agate Chemical Formula

While comparing Piemontite and Agate 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 Piemontite and Agate chemical formula.

• Chemical formula of Piemontite- Ca2Al3(SiO4)(Si2O7)O(OH)
• Chemical formula of Agate- SiO₂

Piemontite and Agate Specific Gravity

Another important criteria for qualitative analysis of gemstones is Piemontite and Agate Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Piemontite and Agate Optical Properties during the identification of gemstone. Specific gravity of Piemontite is 2.60-2.64 whereas that of Agate is 2.60-2.64.
