Goldstone and Lapis lazuli Chemical Formula

While comparing Goldstone and Lapis lazuli 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 Goldstone and Lapis lazuli chemical formula.

  • Chemical formula of Goldstone- Au
  • Chemical formula of Lapis lazuli- The chief constituent Lapis Lazuli is Lazurite, with the following chemical formula: (Na,Ca)8Al6Si6O24(S,SO)4

Goldstone and Lapis lazuli Specific Gravity

Another important criteria for qualitative analysis of gemstones is Goldstone and Lapis lazuli Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Goldstone and Lapis lazuli Optical Properties during the identification of gemstone. Specific gravity of Goldstone is 2.50-3.00 whereas that of Lapis lazuli is 2.50-3.00.
