Biotite and Jasper Physical Properties

Biotite and Jasper Chemical Formula

While comparing Biotite and Jasper 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 Biotite and Jasper chemical formula.

• Chemical formula of Biotite- K(Mg,Fe++)3[AlSi3O10(OH,F)2
• Chemical formula of Jasper- SiO₂

Biotite and Jasper Specific Gravity

Another important criteria for qualitative analysis of gemstones is Biotite and Jasper Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Biotite and Jasper Optical Properties during the identification of gemstone. Specific gravity of Biotite is 2.58-2.91 whereas that of Jasper is 2.58-2.91.
