Narsarsukite and Norbergite Chemical Formula
While comparing Narsarsukite 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 Narsarsukite and Norbergite chemical formula.

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