Ajoite and Lapis lazuli Chemical Formula
While comparing Ajoite 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 Ajoite and Lapis lazuli chemical formula.
- Chemical formula of Ajoite- (K,Na)3Cu20Al3Si29O76(OH)16•~8(H2O)
- Chemical formula of Lapis lazuli- The chief constituent Lapis Lazuli is Lazurite, with the following chemical formula: (Na,Ca)8Al6Si6O24(S,SO)4
Ajoite and Lapis lazuli Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ajoite and Lapis lazuli Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ajoite and Lapis lazuli Optical Properties during the identification of gemstone. Specific gravity of Ajoite is 2.50-3.00 whereas that of Lapis lazuli is 2.50-3.00.
