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

- Chemical formula of Sunstone- Microcline: KAlSi3O8 Oligoclase: (Na,Ca)Al1-2Si3-2O8
Coral and Sunstone Specific Gravity
Another important criteria for qualitative analysis of gemstones is Coral and Sunstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Coral and Sunstone Optical Properties during the identification of gemstone. Specific gravity of Coral is 2.62-2.65 whereas that of Sunstone is 2.62-2.65.
