Sunstone and Pyrope Physical Properties

Sunstone and Pyrope Chemical Formula

While comparing Sunstone and Pyrope 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 Pyrope chemical formula.

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

Sunstone and Pyrope Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sunstone and Pyrope Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Pyrope Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 3.62-3.87 whereas that of Pyrope is 3.62-3.87.
