Variscite and Scolecite Chemical Formula
While comparing Variscite and Scolecite 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 Scolecite chemical formula.
- Chemical formula of Variscite- AlPO4 · 2(H2O)
- Chemical formula of Scolecite- CaAl 2Si 3O 10 · 3H 2OUlrich Henn and Claudio C.
Variscite and Scolecite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Variscite and Scolecite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Variscite and Scolecite Optical Properties during the identification of gemstone. Specific gravity of Variscite is 2.20-2.23 whereas that of Scolecite is 2.20-2.23.
