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

Apatite and Simpsonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Apatite and Simpsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apatite and Simpsonite Optical Properties during the identification of gemstone. Specific gravity of Apatite is Not Available whereas that of Simpsonite is Not Available.
