Pyrope and Lazurite Physical Properties

Pyrope and Lazurite Chemical Formula

While comparing Pyrope and Lazurite 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 Pyrope and Lazurite chemical formula.

• Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Lazurite- (Na,Ca) 8Al 6Si 6O 24(SO 4,S,Cl) 2Ulrich Henn and Claudio C.

Pyrope and Lazurite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrope and Lazurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrope and Lazurite Optical Properties during the identification of gemstone. Specific gravity of Pyrope is 2.75 whereas that of Lazurite is 2.75.
