Variscite and Pollucite Chemical Formula

While comparing Variscite and Pollucite 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 Pollucite chemical formula.

  • Chemical formula of Variscite- AlPO4 · 2(H2O)
  • Chemical formula of Pollucite- (Cs,Na)(AlSi 2O 6) · 0.5H 2OWalter Schumann , Gemstones of the world (2001) More from other references

Variscite and Pollucite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Variscite and Pollucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Variscite and Pollucite Optical Properties during the identification of gemstone. Specific gravity of Variscite is 2.86-2.94 whereas that of Pollucite is 2.86-2.94.
