Pleonast and Oligoclase Physical Properties

Pleonast and Oligoclase Chemical Formula

While comparing Pleonast 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 Pleonast and Oligoclase chemical formula.

Pleonast and Oligoclase Specific Gravity

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