Uvite and Williamsite Physical Properties

Uvite and Williamsite Chemical Formula

While comparing Uvite and Williamsite 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 Uvite and Williamsite chemical formula.

• Chemical formula of Uvite- Ca(Mg 3)MgAl 5(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
• Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)

Uvite and Williamsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Uvite and Williamsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Uvite and Williamsite Optical Properties during the identification of gemstone. Specific gravity of Uvite is 2.51-2.63 whereas that of Williamsite is 2.51-2.63.
