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

Hurlbutite and Foitite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hurlbutite and Foitite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hurlbutite and Foitite Optical Properties during the identification of gemstone. Specific gravity of Hurlbutite is 3.17 whereas that of Foitite is 3.17.
