Ettringite and Diopside Chemical Formula
While comparing Ettringite 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 Ettringite and Diopside chemical formula.

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