Tanzanite and Uvite Physical Properties

Tanzanite and Uvite Chemical Formula

While comparing Tanzanite 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 Tanzanite and Uvite chemical formula.

• Chemical formula of Tanzanite- Ca₂Al₃(SiO₄)₃(OH)
• Chemical formula of Uvite- Ca(Mg 3)MgAl 5(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)

Tanzanite and Uvite Specific Gravity

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