Lepidolite and Lazurite Chemical Formula
While comparing Lepidolite and Lazurite 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 Lepidolite and Lazurite chemical formula.
- Chemical formula of Lepidolite- Mg 3Si 4O 10(OH) 2Ulrich Henn and Claudio C.
- Chemical formula of Lazurite- (Na,Ca) 8Al 6Si 6O 24(SO 4,S,Cl) 2Ulrich Henn and Claudio C.
Lepidolite and Lazurite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lepidolite and Lazurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lepidolite and Lazurite Optical Properties during the identification of gemstone. Specific gravity of Lepidolite is 2.75 whereas that of Lazurite is 2.75.
