While comparing Edenite and Chiastolite 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 Chiastolite chemical formula.
Another important criteria for qualitative analysis of gemstones is Edenite and Chiastolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Edenite and Chiastolite Optical Properties during the identification of gemstone. Specific gravity of Edenite is 3.00-3.15 whereas that of Chiastolite is 3.00-3.15.
