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

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