Neptunite and Pectolite Physical Properties

Neptunite and Pectolite Chemical Formula

While comparing Neptunite and Pectolite 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 Pectolite chemical formula.

• Chemical formula of Neptunite- KNa 2Li(Fe2+ ,Mn2+ ) 2Ti 2Si 8O 24Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Pectolite- Ca 2NaHSi 3O 9Ulrich Henn and Claudio C.

Neptunite and Pectolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Neptunite and Pectolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Neptunite and Pectolite Optical Properties during the identification of gemstone. Specific gravity of Neptunite is 2.74-2.90 whereas that of Pectolite is 2.74-2.90.
