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

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