Jacobsite and Agate Chemical Formula

While comparing Jacobsite and Agate 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 Jacobsite and Agate chemical formula.

Jacobsite and Agate Specific Gravity

Another important criteria for qualitative analysis of gemstones is Jacobsite and Agate Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jacobsite and Agate Optical Properties during the identification of gemstone. Specific gravity of Jacobsite is 2.60-2.64 whereas that of Agate is 2.60-2.64.
