Prase and Steatite Physical Properties

Prase and Steatite Chemical Formula

While comparing Prase 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 Prase and Steatite chemical formula.

• Chemical formula of Prase- SiO 2Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Steatite- Mg 3Si 4O 10(OH) 2Gemdat.org , Management Team (2012)

Prase and Steatite Specific Gravity

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