Sunstone and Steatite Physical Properties

Sunstone and Steatite Chemical Formula

While comparing Sunstone and Steatite 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 Steatite chemical formula.

• Chemical formula of Sunstone- Microcline: KAlSi₃O₈ Oligoclase: (Na,Ca)Al_1-2Si_3-2O₈
• Chemical formula of Steatite- Mg 3Si 4O 10(OH) 2Gemdat.org , Management Team (2012)

Sunstone and Steatite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sunstone and Steatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Steatite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 2.20-2.80 whereas that of Steatite is 2.20-2.80.
