Oligoclase and Diopside Physical Properties

Oligoclase and Diopside Chemical Formula

While comparing Oligoclase and Diopside 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 Oligoclase and Diopside chemical formula.

• Chemical formula of Oligoclase- Na(90-70%)Ca(10-30%)(Al,Si)AlSi 2O 8Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Diopside- CaMgSi₂O₆

Oligoclase and Diopside Specific Gravity

Another important criteria for qualitative analysis of gemstones is Oligoclase and Diopside Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Diopside Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 3.22-3.40 whereas that of Diopside is 3.22-3.40.
