Aegirine and Nepheline Chemical Formula

While comparing Aegirine and Nepheline 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 Aegirine and Nepheline chemical formula.

  • Chemical formula of Aegirine- (Na,Fe,Ca)Si 2O 6Ulrich Henn and Claudio C.
  • Chemical formula of Nepheline- Na 3(Na,K)Al 4Si 4O 16Ulrich Henn and Claudio C.

Aegirine and Nepheline Specific Gravity

Another important criteria for qualitative analysis of gemstones is Aegirine and Nepheline Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Aegirine and Nepheline Optical Properties during the identification of gemstone. Specific gravity of Aegirine is 2.55-2.65 whereas that of Nepheline is 2.55-2.65.
