Sunstone and Rubellite Chemical Formula
While comparing Sunstone 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 Sunstone and Rubellite chemical formula.
- Chemical formula of Sunstone- Microcline: KAlSi3O8 Oligoclase: (Na,Ca)Al1-2Si3-2O8
- 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.
Sunstone and Rubellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sunstone and Rubellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Rubellite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 3.01-3.06 whereas that of Rubellite is 3.01-3.06.
