Andesine and Scapolite Chemical Formula

While comparing Andesine and Scapolite 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 Andesine and Scapolite chemical formula.

  • Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8
  • Chemical formula of Scapolite- Na 4Al 3Si 9O 24Cl to Ca 4Al 6Si 6O 24(CO 3,SO 4)Walter Schumann , Gemstones of the world (2001) More from other references

Andesine and Scapolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Andesine and Scapolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andesine and Scapolite Optical Properties during the identification of gemstone. Specific gravity of Andesine is 2.58-2.74 whereas that of Scapolite is 2.58-2.74.
