Herderite and Humite Physical Properties

Herderite and Humite Chemical Formula

While comparing Herderite 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 Herderite and Humite chemical formula.

• Chemical formula of Herderite- CaBePO 4(F,OH)Ulrich Henn and Claudio C.
• Chemical formula of Humite- (Mg,Fe2+ ) 7(SiO 4) 3(F,OH) 2Anthony et al , Handbook of mineralogy (2001)

Herderite and Humite Specific Gravity

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