Ametrine and Oligoclase Physical Properties

Ametrine and Oligoclase Chemical Formula

While comparing Ametrine 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 Ametrine and Oligoclase chemical formula.

• Chemical formula of Oligoclase- Na(90-70%)Ca(10-30%)(Al,Si)AlSi 2O 8Michael O’Donoghue , Gems, Sixth Edition (2006)

Ametrine and Oligoclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Ametrine and Oligoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ametrine and Oligoclase Optical Properties during the identification of gemstone. Specific gravity of Ametrine is 2.62-2.67 whereas that of Oligoclase is 2.62-2.67.
