Foitite and Hexagonite Chemical Formula
While comparing Foitite and Hexagonite 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 Foitite and Hexagonite chemical formula.

Foitite and Hexagonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Foitite and Hexagonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Foitite and Hexagonite Optical Properties during the identification of gemstone. Specific gravity of Foitite is 2.98-3.03 whereas that of Hexagonite is 2.98-3.03.
