Poudretteite and Diaspore Chemical Formula
While comparing Poudretteite 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 Poudretteite and Diaspore chemical formula.

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