Actinolite and Steatite Chemical Formula
While comparing Actinolite 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 Actinolite and Steatite chemical formula.

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