Realgar and Sunstone Physical Properties

Realgar and Sunstone Chemical Formula

While comparing Realgar 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 Realgar and Sunstone chemical formula.

• Chemical formula of Realgar- AsSMichael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Sunstone- Microcline: KAlSi₃O₈ Oligoclase: (Na,Ca)Al_1-2Si_3-2O₈

Realgar and Sunstone Specific Gravity

Another important criteria for qualitative analysis of gemstones is Realgar and Sunstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Realgar and Sunstone Optical Properties during the identification of gemstone. Specific gravity of Realgar is 2.62-2.65 whereas that of Sunstone is 2.62-2.65.
