Chlorapatite and Neptunite Chemical Formula
While comparing Chlorapatite and Neptunite 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 Chlorapatite and Neptunite chemical formula.

Chlorapatite and Neptunite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chlorapatite and Neptunite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chlorapatite and Neptunite Optical Properties during the identification of gemstone. Specific gravity of Chlorapatite is 3.19-3.23 whereas that of Neptunite is 3.19-3.23.
