Thulite and Uvite Chemical Formula
While comparing Thulite 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 Thulite and Uvite chemical formula.
- Chemical formula of Thulite- 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)
Thulite and Uvite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Thulite and Uvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thulite and Uvite Optical Properties during the identification of gemstone. Specific gravity of Thulite is 2.97-3.14 whereas that of Uvite is 2.97-3.14.
