Humite and Erythrite Physical Properties

Humite and Erythrite Chemical Formula

While comparing Humite and Erythrite 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 Humite and Erythrite chemical formula.

• Chemical formula of Humite- (Mg,Fe2+ ) 7(SiO 4) 3(F,OH) 2Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Erythrite- Co3(AsO4)2•8(H2O)

Humite and Erythrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Humite and Erythrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Humite and Erythrite Optical Properties during the identification of gemstone. Specific gravity of Humite is 3.06 whereas that of Erythrite is 3.06.
