Sunstone and Prehnite Chemical Formula
While comparing Sunstone and Prehnite 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 Prehnite chemical formula.
- Chemical formula of Sunstone- Microcline: KAlSi3O8 Oligoclase: (Na,Ca)Al1-2Si3-2O8
- Chemical formula of Prehnite- Ca2Al2Si3O12(OH)
Sunstone and Prehnite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sunstone and Prehnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Prehnite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 2.80-2.95 whereas that of Prehnite is 2.80-2.95.
