Piemontite and Triplite Physical Properties

Piemontite and Triplite Chemical Formula

While comparing Piemontite and Triplite 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 Triplite chemical formula.

• Chemical formula of Piemontite- Ca2Al3(SiO4)(Si2O7)O(OH)
• Chemical formula of Triplite- (Mn2+ ,Fe2+ ,Mg,Ca) 2(PO 4)(F,OH)Michael O’Donoghue , Gems, Sixth Edition (2006)

Piemontite and Triplite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Piemontite and Triplite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Piemontite and Triplite Optical Properties during the identification of gemstone. Specific gravity of Piemontite is 3.85-3.94 whereas that of Triplite is 3.85-3.94.
