Hexagonite and Lapis lazuli Chemical Formula
While comparing Hexagonite 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 Hexagonite and Lapis lazuli chemical formula.
- Chemical formula of Hexagonite- Ca 2Mg 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
- Chemical formula of Lapis lazuli- The chief constituent Lapis Lazuli is Lazurite, with the following chemical formula: (Na,Ca)8Al6Si6O24(S,SO)4
Hexagonite and Lapis lazuli Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hexagonite and Lapis lazuli Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hexagonite and Lapis lazuli Optical Properties during the identification of gemstone. Specific gravity of Hexagonite is 2.50-3.00 whereas that of Lapis lazuli is 2.50-3.00.
