Spinel and Binghamite Physical Properties

Spinel and Binghamite Chemical Formula

While comparing Spinel 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 Spinel and Binghamite chemical formula.

• Chemical formula of Spinel- MgAl₂O₄
• Chemical formula of Binghamite- SiO 2Arthur Thomas , Gemstones (2009)

Spinel and Binghamite Specific Gravity

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