Agate and Neptunite Physical Properties

Agate and Neptunite Chemical Formula

While comparing Agate and Neptunite 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 Agate and Neptunite chemical formula.

• Chemical formula of Agate- SiO₂
• Chemical formula of Neptunite- KNa 2Li(Fe2+ ,Mn2+ ) 2Ti 2Si 8O 24Michael O’Donoghue , Gems, Sixth Edition (2006)

Agate and Neptunite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Agate and Neptunite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Agate and Neptunite Optical Properties during the identification of gemstone. Specific gravity of Agate is 3.19-3.23 whereas that of Neptunite is 3.19-3.23.
