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

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