Riesling Beryl and Oligoclase Chemical Formula
While comparing Riesling Beryl and Oligoclase 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 Riesling Beryl and Oligoclase chemical formula.
- Chemical formula of Riesling Beryl- Al 2Be 3Si 6O 18Martin H.
- Chemical formula of Oligoclase- Na(90-70%)Ca(10-30%)(Al,Si)AlSi 2O 8Michael OâDonoghue , Gems, Sixth Edition (2006)
Riesling Beryl and Oligoclase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Riesling Beryl and Oligoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Riesling Beryl and Oligoclase Optical Properties during the identification of gemstone. Specific gravity of Riesling Beryl is 2.62-2.67 whereas that of Oligoclase is 2.62-2.67.
