Jet and Apatite Chemical Formula

While comparing Jet 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 Jet and Apatite chemical formula.

Jet and Apatite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Jet and Apatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jet Vs Apatite during the identification of gemstone. Specific gravity of Jet is whereas that of Apatite is .
