Diopside and Rubellite Chemical Formula
While comparing Diopside and Rubellite 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 Rubellite chemical formula.
- Chemical formula of Diopside- CaMgSi2O6
- Chemical formula of Rubellite- 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 Rubellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Diopside and Rubellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diopside and Rubellite Optical Properties during the identification of gemstone. Specific gravity of Diopside is 3.01-3.06 whereas that of Rubellite is 3.01-3.06.
