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

Jacobsite and Jade Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jacobsite and Jade Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jacobsite and Jade Optical Properties during the identification of gemstone. Specific gravity of Jacobsite is 2.90-3.38 whereas that of Jade is 2.90-3.38.
