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

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