Pyrope and Sunstone Physical Properties

Pyrope and Sunstone Chemical Formula

While comparing Pyrope 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 Pyrope and Sunstone chemical formula.

• Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Sunstone- Microcline: KAlSi₃O₈ Oligoclase: (Na,Ca)Al_1-2Si_3-2O₈

Pyrope and Sunstone Specific Gravity

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