Steatite and Selenite Physical Properties

Steatite and Selenite Chemical Formula

While comparing Steatite and Selenite 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 Selenite chemical formula.

• Chemical formula of Steatite- Mg 3Si 4O 10(OH) 2Gemdat.org , Management Team (2012)
• Chemical formula of Selenite- CaSO4·2H2O

Steatite and Selenite Specific Gravity

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