Sunstone and Brucite Physical Properties

Sunstone and Brucite Chemical Formula

While comparing Sunstone and Brucite 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 Brucite chemical formula.

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

Sunstone and Brucite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sunstone and Brucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Brucite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 2.39 whereas that of Brucite is 2.39.
