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

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