Sunstone and Thulite Physical Properties

Sunstone and Thulite Chemical Formula

While comparing Sunstone and Thulite 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 Thulite chemical formula.

• Chemical formula of Sunstone- Microcline: KAlSi₃O₈ Oligoclase: (Na,Ca)Al_1-2Si_3-2O₈
• Chemical formula of Thulite- Ca₂Al₃(SiO₄)₃(OH)

Sunstone and Thulite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sunstone and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Thulite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 3.1 whereas that of Thulite is 3.1.
