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

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