While comparing Diopside and Hayne 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 Diopside and Hayne chemical formula.
Another important criteria for qualitative analysis of gemstones is Diopside and Hayne Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diopside and Hayne Optical Properties during the identification of gemstone. Specific gravity of Diopside is 2.40-2.50 whereas that of Hayne is 2.40-2.50.
