Cuprite and Oligoclase Chemical Formula
While comparing Cuprite 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 Cuprite and Oligoclase chemical formula.

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