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

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