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

Oligoclase and Cavansite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Oligoclase and Cavansite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Cavansite Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 2.25-2.33 whereas that of Cavansite is 2.25-2.33.
