Goshenite and Lapis lazuli Chemical Formula
While comparing Goshenite 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 Goshenite and Lapis lazuli chemical formula.
- Chemical formula of Goshenite- Be3Al2SiO6
- Chemical formula of Lapis lazuli- The chief constituent Lapis Lazuli is Lazurite, with the following chemical formula: (Na,Ca)8Al6Si6O24(S,SO)4
Goshenite and Lapis lazuli Specific Gravity
Another important criteria for qualitative analysis of gemstones is Goshenite and Lapis lazuli Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Goshenite and Lapis lazuli Optical Properties during the identification of gemstone. Specific gravity of Goshenite is 2.50-3.00 whereas that of Lapis lazuli is 2.50-3.00.
