Simpsonite and Sunstone Chemical Formula
While comparing Simpsonite 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 Simpsonite and Sunstone chemical formula.
- Chemical formula of Simpsonite- Al 4(Ta,Nb) 3(O,OH,F) 14Ulrich Henn and Claudio C.
- Chemical formula of Sunstone- Microcline: KAlSi3O8 Oligoclase: (Na,Ca)Al1-2Si3-2O8
Simpsonite and Sunstone Specific Gravity
Another important criteria for qualitative analysis of gemstones is Simpsonite and Sunstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Simpsonite and Sunstone Optical Properties during the identification of gemstone. Specific gravity of Simpsonite is 2.62-2.65 whereas that of Sunstone is 2.62-2.65.
