Piemontite and Pectolite Physical Properties

Piemontite and Pectolite Chemical Formula

While comparing Piemontite and Pectolite 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 Pectolite chemical formula.

• Chemical formula of Piemontite- Ca2Al3(SiO4)(Si2O7)O(OH)
• Chemical formula of Pectolite- Ca 2NaHSi 3O 9Ulrich Henn and Claudio C.

Piemontite and Pectolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Piemontite and Pectolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Piemontite and Pectolite Optical Properties during the identification of gemstone. Specific gravity of Piemontite is 2.74-2.90 whereas that of Pectolite is 2.74-2.90.
