Gyrolite and Apatite Chemical Formula

While comparing Gyrolite and Apatite 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 Gyrolite and Apatite chemical formula.

  • Chemical formula of Gyrolite- NaCa16Si23AlO60(OH)8•64(H2O)
  • Chemical formula of Apatite- Ca 5(PO 4) 3(F,OH,Cl)Walter Schumann , Gemstones of the world (2001) More from other references

Gyrolite and Apatite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gyrolite and Apatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gyrolite and Apatite Optical Properties during the identification of gemstone. Specific gravity of Gyrolite is 3.16-3.23 whereas that of Apatite is 3.16-3.23.
