Dioptase and Schorl Physical Properties

Dioptase and Schorl Chemical Formula

While comparing Dioptase 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 Dioptase and Schorl chemical formula.

Dioptase and Schorl Specific Gravity

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