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

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