Andesine and Dolomite Chemical Formula

While comparing Andesine and Dolomite 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 Dolomite chemical formula.

  • Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8
  • Chemical formula of Dolomite- CaMg(CO 3) 2Michael O’Donoghue , Gems, Sixth Edition (2006) More from other references

Andesine and Dolomite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Andesine and Dolomite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andesine and Dolomite Optical Properties during the identification of gemstone. Specific gravity of Andesine is 2.80-2.95 whereas that of Dolomite is 2.80-2.95.
