Chalcedony and Humite Physical Properties

Chalcedony and Humite Chemical Formula

While comparing Chalcedony 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 Chalcedony and Humite chemical formula.

• Chemical formula of Chalcedony- SiO₂
• Chemical formula of Humite- (Mg,Fe2+ ) 7(SiO 4) 3(F,OH) 2Anthony et al , Handbook of mineralogy (2001)

Chalcedony and Humite Specific Gravity

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