Piemontite and Inderite Physical Properties

Piemontite and Inderite Chemical Formula

While comparing Piemontite and Inderite 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 Inderite chemical formula.

• Chemical formula of Piemontite- Ca2Al3(SiO4)(Si2O7)O(OH)
• Chemical formula of Inderite- MgB 3O 3(OH) 5 · 5H 2OMichael O’Donoghue , Gems, Sixth Edition (2006)

Piemontite and Inderite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Piemontite and Inderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Piemontite and Inderite Optical Properties during the identification of gemstone. Specific gravity of Piemontite is 1.79 whereas that of Inderite is 1.79.
