Seraphinite and Spinel Chemical Formula

While comparing Seraphinite and Spinel 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 Seraphinite and Spinel chemical formula.

Seraphinite and Spinel Specific Gravity

Another important criteria for qualitative analysis of gemstones is Seraphinite and Spinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Seraphinite and Spinel Optical Properties during the identification of gemstone. Specific gravity of Seraphinite is 3.64-3.66 whereas that of Spinel is 3.64-3.66.
