While comparing Dallasite and Elaeolite 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 Dallasite and Elaeolite chemical formula.
Another important criteria for qualitative analysis of gemstones is Dallasite and Elaeolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dallasite and Elaeolite Optical Properties during the identification of gemstone. Specific gravity of Dallasite is 2.55-2.67 whereas that of Elaeolite is 2.55-2.67.
