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

Anglesite and Schorl Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anglesite and Schorl Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anglesite and Schorl Optical Properties during the identification of gemstone. Specific gravity of Anglesite is 3.18-3.22 whereas that of Schorl is 3.18-3.22.
