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

Diopside and Powellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Diopside and Powellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diopside and Powellite Optical Properties during the identification of gemstone. Specific gravity of Diopside is 4.23 whereas that of Powellite is 4.23.
