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

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