Heliotrope and Hematite Physical Properties

Heliotrope and Hematite Chemical Formula

While comparing Heliotrope and Hematite 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 Heliotrope and Hematite chemical formula.

• Chemical formula of Heliotrope- SiO2
• Chemical formula of Hematite- Fe 2O 3Arthur Thomas , Gemstones (2009)

Heliotrope and Hematite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Heliotrope and Hematite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Heliotrope and Hematite Optical Properties during the identification of gemstone. Specific gravity of Heliotrope is 5.00-5.30 whereas that of Hematite is 5.00-5.30.
