Jet and Jacobsite Chemical Formula
While comparing Jet and Jacobsite 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 Jet and Jacobsite chemical formula.

Jet and Jacobsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jet and Jacobsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jet and Jacobsite Optical Properties during the identification of gemstone. Specific gravity of Jet is 4.76-5.03 whereas that of Jacobsite is 4.76-5.03.
