Schorl and Diaspore Chemical Formula

While comparing Schorl and Diaspore 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 Schorl and Diaspore chemical formula.

Schorl and Diaspore Specific Gravity

Another important criteria for qualitative analysis of gemstones is Schorl and Diaspore Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Schorl and Diaspore Optical Properties during the identification of gemstone. Specific gravity of Schorl is 3.30-3.40 whereas that of Diaspore is 3.30-3.40.
