Albite and Lapis lazuli Chemical Formula
While comparing Albite 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 Albite and Lapis lazuli chemical formula.
- Chemical formula of Albite- NaAlSi 3O 8Michael OâDonoghue , Gems, Sixth Edition (2006)
- Chemical formula of Lapis lazuli- The chief constituent Lapis Lazuli is Lazurite, with the following chemical formula: (Na,Ca)8Al6Si6O24(S,SO)4
Albite and Lapis lazuli Specific Gravity
Another important criteria for qualitative analysis of gemstones is Albite and Lapis lazuli Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Albite and Lapis lazuli Optical Properties during the identification of gemstone. Specific gravity of Albite is 2.50-3.00 whereas that of Lapis lazuli is 2.50-3.00.
