Chrysoprase and Norbergite Chemical Formula
While comparing Chrysoprase 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 Chrysoprase and Norbergite chemical formula.
- Chemical formula of Chrysoprase- SiO2 (with a high level of nickel impurities )
- Chemical formula of Norbergite- Mg 3(SiO 4)(F,OH) 2Anthony et al , Handbook of Mineralogy (2001)
Chrysoprase and Norbergite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysoprase and Norbergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Norbergite Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 3.177 whereas that of Norbergite is 3.177.
