Verdite and Lepidolite Chemical Formula
While comparing Verdite and Lepidolite 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 Verdite and Lepidolite chemical formula.
- Chemical formula of Verdite- NaFeS2•2(H2O)
- Chemical formula of Lepidolite- Mg 3Si 4O 10(OH) 2Ulrich Henn and Claudio C.
Verdite and Lepidolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Verdite and Lepidolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Verdite and Lepidolite Optical Properties during the identification of gemstone. Specific gravity of Verdite is 2.80-2.90 whereas that of Lepidolite is 2.80-2.90.
