Nepouite and Siderite Physical Properties

Nepouite and Siderite Chemical Formula

While comparing Nepouite and Siderite 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 Nepouite and Siderite chemical formula.

• Chemical formula of Siderite- Fe2+ CO 3Michael O’Donoghue , Gems, Sixth Edition (2006) More from other references

Nepouite and Siderite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Nepouite and Siderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nepouite and Siderite Optical Properties during the identification of gemstone. Specific gravity of Nepouite is 3.83-3.89 whereas that of Siderite is 3.83-3.89.
