Calcite and Humite Physical Properties

Calcite and Humite Chemical Formula

While comparing Calcite 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 Calcite and Humite chemical formula.

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

Calcite and Humite Specific Gravity

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