Piemontite and Quartz Physical Properties

Piemontite and Quartz Chemical Formula

While comparing Piemontite and Quartz 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 Quartz chemical formula.

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

Piemontite and Quartz Specific Gravity

Another important criteria for qualitative analysis of gemstones is Piemontite and Quartz Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Piemontite and Quartz Optical Properties during the identification of gemstone. Specific gravity of Piemontite is 2.65 whereas that of Quartz is 2.65.
