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

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