Diopside and Verdelite Chemical Formula
While comparing Diopside and Verdelite 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 Verdelite chemical formula.
- Chemical formula of Diopside- CaMgSi2O6
- Chemical formula of Verdelite- Na(Li 1.5Al 1.5)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012) Formula given for elbaite.
Diopside and Verdelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Diopside and Verdelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diopside and Verdelite Optical Properties during the identification of gemstone. Specific gravity of Diopside is 2.90-3.40 whereas that of Verdelite is 2.90-3.40.
