While comparing Cacoxenite and Diopside 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 Cacoxenite and Diopside chemical formula.
Another important criteria for qualitative analysis of gemstones is Cacoxenite and Diopside Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cacoxenite and Diopside Optical Properties during the identification of gemstone. Specific gravity of Cacoxenite is 3.22-3.40 whereas that of Diopside is 3.22-3.40.
