Lazulite and Prasiolite Chemical Formula

While comparing Lazulite and Prasiolite 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 Lazulite and Prasiolite chemical formula.

  • Chemical formula of Lazulite- (Mg,Fe)Al 2(PO 4) 2(OH) 2Arthur Thomas , Gemstones (2009) More from other references
  • Chemical formula of Prasiolite- SiO 2Ulrich Henn and Claudio C.

Lazulite and Prasiolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lazulite and Prasiolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazulite and Prasiolite Optical Properties during the identification of gemstone. Specific gravity of Lazulite is 2.65 whereas that of Prasiolite is 2.65.
