Norbergite and Forsterite Physical Properties

Norbergite and Forsterite Chemical Formula

While comparing Norbergite and Forsterite 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 Norbergite and Forsterite chemical formula.

• Chemical formula of Norbergite- Mg 3(SiO 4)(F,OH) 2Anthony et al , Handbook of Mineralogy (2001)
• Chemical formula of Forsterite- Mg 2SiO 4Michael O’Donoghue , Gems, Sixth Edition (2006)

Norbergite and Forsterite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Norbergite and Forsterite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Norbergite and Forsterite Optical Properties during the identification of gemstone. Specific gravity of Norbergite is 3.23-3.26 whereas that of Forsterite is 3.23-3.26.
