Xonotlite and Lazurite Physical Properties

Xonotlite and Lazurite Chemical Formula

While comparing Xonotlite 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 Xonotlite and Lazurite chemical formula.

• Chemical formula of Xonotlite- Ca 6Si 6O 17(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Lazurite- (Na,Ca) 8Al 6Si 6O 24(SO 4,S,Cl) 2Ulrich Henn and Claudio C.

Xonotlite and Lazurite Specific Gravity

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