Idocrase and Hematite Physical Properties

Idocrase and Hematite Chemical Formula

While comparing Idocrase 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 Idocrase and Hematite chemical formula.

• Chemical formula of Idocrase- Ca10(Mg,Fe)2(Si2O7)2(SiO4)2O(OH)2
• Chemical formula of Hematite- Fe 2O 3Arthur Thomas , Gemstones (2009)

Idocrase and Hematite Specific Gravity

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