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

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