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

Oligoclase and Aragonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Oligoclase and Aragonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Aragonite Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 2.93-2.96 whereas that of Aragonite is 2.93-2.96.
