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

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