Hematite and Emerald Physical Properties

Hematite and Emerald Chemical Formula

While comparing Hematite and Emerald 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 Emerald chemical formula.

• Chemical formula of Hematite- Fe 2O 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Emerald- Be₃Al₂SiO₆

Hematite and Emerald Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hematite and Emerald Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hematite and Emerald Optical Properties during the identification of gemstone. Specific gravity of Hematite is 2.67-2.78 whereas that of Emerald is 2.67-2.78.
