Piemontite and Axinite Physical Properties

Piemontite and Axinite Chemical Formula

While comparing Piemontite and Axinite 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 Axinite chemical formula.

• Chemical formula of Piemontite- Ca2Al3(SiO4)(Si2O7)O(OH)
• Chemical formula of Axinite- (Ca,Fe,Mn,Mg) 3Al 2BSi 4O 15(OH)Walter Schumann , Gemstones of the world (2001) More from other references

Piemontite and Axinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Piemontite and Axinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Piemontite and Axinite Optical Properties during the identification of gemstone. Specific gravity of Piemontite is 3.26-3.36 whereas that of Axinite is 3.26-3.36.
