Hureaulite and Spinel Physical Properties

Hureaulite and Spinel Chemical Formula

While comparing Hureaulite and Spinel 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 Hureaulite and Spinel chemical formula.

• Chemical formula of Hureaulite- Mn2+5(PO 4) 2(PO 3OH) 2 · 4H 2O)Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Spinel- MgAl₂O₄

Hureaulite and Spinel Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hureaulite and Spinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hureaulite and Spinel Optical Properties during the identification of gemstone. Specific gravity of Hureaulite is 3.64-3.66 whereas that of Spinel is 3.64-3.66.
