Variscite and Uvarovite Chemical Formula
While comparing Variscite and Uvarovite 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 Variscite and Uvarovite chemical formula.
- Chemical formula of Variscite- AlPO4 · 2(H2O)
- Chemical formula of Uvarovite- Ca 3Cr 2(SiO 4) 3Ulrich Henn and Claudio C.
Variscite and Uvarovite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Variscite and Uvarovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Variscite and Uvarovite Optical Properties during the identification of gemstone. Specific gravity of Variscite is 3.77 whereas that of Uvarovite is 3.77.
