Sunstone and Moonstone Physical Properties

Sunstone and Moonstone Chemical Formula

While comparing Sunstone and Moonstone 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 Moonstone chemical formula.

• Chemical formula of Sunstone- Microcline: KAlSi₃O₈ Oligoclase: (Na,Ca)Al_1-2Si_3-2O₈
• Chemical formula of Moonstone- Plagioclase Feldspar s: (Na,Ca)Al_1-2Si_3-2O₈ Orthoclase Feldspar : KAlSi₃O₈

Sunstone and Moonstone Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sunstone and Moonstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Moonstone Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 2.56-2.60 whereas that of Moonstone is 2.56-2.60.
