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

Norbergite and Rhodolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Norbergite and Rhodolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Norbergite and Rhodolite Optical Properties during the identification of gemstone. Specific gravity of Norbergite is 3.84 whereas that of Rhodolite is 3.84.
