Faustite and Sphene Physical Properties

Faustite and Sphene Chemical Formula

While comparing Faustite and Sphene 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 Faustite and Sphene chemical formula.

• Chemical formula of Faustite- (Zn,Cu)Al 6(PO 4) 4(OH) 8 · 4H 2OMichael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Sphene- CaTiSiO5

Faustite and Sphene Specific Gravity

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