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

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