Humite and Lepidocrocite Physical Properties

Humite and Lepidocrocite Chemical Formula

While comparing Humite and Lepidocrocite 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 Lepidocrocite chemical formula.

• Chemical formula of Humite- (Mg,Fe2+ ) 7(SiO 4) 3(F,OH) 2Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Lepidocrocite- FeO(OH)

Humite and Lepidocrocite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Humite and Lepidocrocite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Humite and Lepidocrocite Optical Properties during the identification of gemstone. Specific gravity of Humite is 4 whereas that of Lepidocrocite is 4.
