Malachite and Norbergite Chemical Formula
While comparing Malachite 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 Malachite and Norbergite chemical formula.
- Chemical formula of Malachite- Cu2CO3(OH)2
- Chemical formula of Norbergite- Mg 3(SiO 4)(F,OH) 2Anthony et al , Handbook of Mineralogy (2001)
Malachite and Norbergite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Malachite and Norbergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Malachite and Norbergite Optical Properties during the identification of gemstone. Specific gravity of Malachite is 3.177 whereas that of Norbergite is 3.177.
