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

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