Piemontite and Chalcopyrite Physical Properties

Piemontite and Chalcopyrite Chemical Formula

While comparing Piemontite and Chalcopyrite 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 Chalcopyrite chemical formula.

• Chemical formula of Piemontite- Ca2Al3(SiO4)(Si2O7)O(OH)
• Chemical formula of Chalcopyrite- CuFeS 2Anthony et al , Handbook of mineralogy (2001)

Piemontite and Chalcopyrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Piemontite and Chalcopyrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Piemontite and Chalcopyrite Optical Properties during the identification of gemstone. Specific gravity of Piemontite is 4.1-4.3 whereas that of Chalcopyrite is 4.1-4.3.
