Topaz and Uvite Physical Properties

Topaz and Uvite Chemical Formula

While comparing Topaz 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 Topaz and Uvite chemical formula.

• Chemical formula of Topaz- Al₂SiO₄(F,OH)₂
• Chemical formula of Uvite- Ca(Mg 3)MgAl 5(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)

Topaz and Uvite Specific Gravity

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