Zoisite and Norbergite Physical Properties

Zoisite and Norbergite Chemical Formula

While comparing Zoisite and Norbergite 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 Zoisite and Norbergite chemical formula.

• Chemical formula of Zoisite- Ca₂Al₃(SiO₄)₃(OH)
• Chemical formula of Norbergite- Mg 3(SiO 4)(F,OH) 2Anthony et al , Handbook of Mineralogy (2001)

Zoisite and Norbergite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Zoisite and Norbergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zoisite and Norbergite Optical Properties during the identification of gemstone. Specific gravity of Zoisite is 3.177 whereas that of Norbergite is 3.177.
