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

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