Steatite and Actinolite Chemical Formula
While comparing Steatite and Actinolite 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 Actinolite chemical formula.
- Chemical formula of Steatite- Mg 3Si 4O 10(OH) 2Gemdat.org , Management Team (2012)

Steatite and Actinolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Steatite and Actinolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Steatite and Actinolite Optical Properties during the identification of gemstone. Specific gravity of Steatite is 3.00 whereas that of Actinolite is 3.00.
