Hibschite and Diaspore Chemical Formula

While comparing Hibschite 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 Hibschite and Diaspore chemical formula.

Hibschite and Diaspore Specific Gravity

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