Adamite and Nepouite Physical Properties

Adamite and Nepouite Chemical Formula

While comparing Adamite and Nepouite 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 Adamite and Nepouite chemical formula.

• Chemical formula of Adamite- Zn 2(AsO 4)(OH)Michael O’Donoghue , Gems, Sixth edition (2006)
• Chemical formula of Nepouite- Ni3(Si2O5)(OH)4

Adamite and Nepouite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Adamite and Nepouite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Adamite and Nepouite Optical Properties during the identification of gemstone. Specific gravity of Adamite is 3.18-3.24 whereas that of Nepouite is 3.18-3.24.
