Williamsite and Sunstone Physical Properties

Williamsite and Sunstone Chemical Formula

While comparing Williamsite 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 Williamsite and Sunstone chemical formula.

• Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Sunstone- Microcline: KAlSi₃O₈ Oligoclase: (Na,Ca)Al_1-2Si_3-2O₈

Williamsite and Sunstone Specific Gravity

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