Sunstone and Phosgenite Chemical Formula
While comparing Sunstone and Phosgenite 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 Sunstone and Phosgenite chemical formula.
- Chemical formula of Sunstone- Microcline: KAlSi3O8 Oligoclase: (Na,Ca)Al1-2Si3-2O8

Sunstone and Phosgenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sunstone and Phosgenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Phosgenite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 6.13 whereas that of Phosgenite is 6.13.
