Steatite and Williamsite Chemical Formula

While comparing Steatite and Williamsite 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 Steatite and Williamsite chemical formula.

  • Chemical formula of Steatite- Mg 3Si 4O 10(OH) 2Gemdat.org , Management Team (2012)
  • Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)

Steatite and Williamsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Steatite and Williamsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Steatite and Williamsite Optical Properties during the identification of gemstone. Specific gravity of Steatite is 2.51-2.63 whereas that of Williamsite is 2.51-2.63.
