Oligoclase and Simpsonite Chemical Formula

While comparing Oligoclase and Simpsonite 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 Simpsonite chemical formula.

Oligoclase and Simpsonite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Oligoclase and Simpsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Simpsonite Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is Not Available whereas that of Simpsonite is Not Available.
