Kyanite and Binghamite Physical Properties

Kyanite and Binghamite Chemical Formula

While comparing Kyanite and Binghamite 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 Kyanite and Binghamite chemical formula.

• Chemical formula of Binghamite- SiO 2Arthur Thomas , Gemstones (2009)

Kyanite and Binghamite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Kyanite and Binghamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kyanite and Binghamite Optical Properties during the identification of gemstone. Specific gravity of Kyanite is 2.55-2.70 whereas that of Binghamite is 2.55-2.70.
