Idocrase and Humite Physical Properties

Idocrase and Humite Chemical Formula

While comparing Idocrase and Humite 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 Humite chemical formula.

• Chemical formula of Idocrase- Ca10(Mg,Fe)2(Si2O7)2(SiO4)2O(OH)2
• Chemical formula of Humite- (Mg,Fe2+ ) 7(SiO 4) 3(F,OH) 2Anthony et al , Handbook of mineralogy (2001)

Idocrase and Humite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Idocrase and Humite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Idocrase and Humite Optical Properties during the identification of gemstone. Specific gravity of Idocrase is 3.20-3.32 whereas that of Humite is 3.20-3.32.
