Clinochlore and Staurolite Chemical Formula
While comparing Clinochlore and Staurolite 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 Clinochlore and Staurolite chemical formula.

Clinochlore and Staurolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Clinochlore and Staurolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Clinochlore and Staurolite Optical Properties during the identification of gemstone. Specific gravity of Clinochlore is 3.7-3.8 whereas that of Staurolite is 3.7-3.8.
