Hematite and Hessonite Physical Properties

Hematite and Hessonite Chemical Formula

While comparing Hematite and Hessonite 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 Hessonite chemical formula.

• Chemical formula of Hematite- Fe 2O 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Hessonite- Ca3Al2(SiO4)3

Hematite and Hessonite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hematite and Hessonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hematite and Hessonite Optical Properties during the identification of gemstone. Specific gravity of Hematite is 3.55-3.73 whereas that of Hessonite is 3.55-3.73.
