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

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