Variscite and Williamsite Chemical Formula
While comparing Variscite 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 Variscite and Williamsite chemical formula.
- Chemical formula of Variscite- AlPO4 · 2(H2O)
- Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)
Variscite and Williamsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Variscite and Williamsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Variscite and Williamsite Optical Properties during the identification of gemstone. Specific gravity of Variscite is 2.51-2.63 whereas that of Williamsite is 2.51-2.63.
