Diopside and Holmquistite Chemical Formula
While comparing Diopside and Holmquistite 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 Holmquistite chemical formula.
- Chemical formula of Diopside- CaMgSi2O6
- Chemical formula of Holmquistite- Li 2[(Mg,Fe2+ ) 3Al 2]Si 8O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)
Diopside and Holmquistite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Diopside and Holmquistite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diopside and Holmquistite Optical Properties during the identification of gemstone. Specific gravity of Diopside is 2.95-3.13 whereas that of Holmquistite is 2.95-3.13.
