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

Steatite and Apatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Steatite and Apatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Steatite and Apatite Optical Properties during the identification of gemstone. Specific gravity of Steatite is 3.16-3.23 whereas that of Apatite is 3.16-3.23.
