Hematite and Piemontite Physical Properties

Hematite and Piemontite Chemical Formula

While comparing Hematite and Piemontite 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 Hematite and Piemontite chemical formula.

• Chemical formula of Hematite- Fe 2O 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Piemontite- Ca2Al3(SiO4)(Si2O7)O(OH)

Hematite and Piemontite Specific Gravity

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