Neptunite and Lepidocrocite Physical Properties

Neptunite and Lepidocrocite Chemical Formula

While comparing Neptunite and Lepidocrocite 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 Neptunite and Lepidocrocite chemical formula.

• Chemical formula of Neptunite- KNa 2Li(Fe2+ ,Mn2+ ) 2Ti 2Si 8O 24Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Lepidocrocite- FeO(OH)

Neptunite and Lepidocrocite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Neptunite and Lepidocrocite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Neptunite and Lepidocrocite Optical Properties during the identification of gemstone. Specific gravity of Neptunite is 4 whereas that of Lepidocrocite is 4.
