Faustite and Uvite Physical Properties

Faustite and Uvite Chemical Formula

While comparing Faustite and Uvite 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 Uvite 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 Uvite- Ca(Mg 3)MgAl 5(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)

Faustite and Uvite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Faustite and Uvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Faustite and Uvite Optical Properties during the identification of gemstone. Specific gravity of Faustite is 2.97-3.14 whereas that of Uvite is 2.97-3.14.
