Seraphinite and Gahnite Chemical Formula
While comparing Seraphinite and Gahnite 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 Gahnite chemical formula.

Seraphinite and Gahnite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Seraphinite and Gahnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Seraphinite and Gahnite Optical Properties during the identification of gemstone. Specific gravity of Seraphinite is 4.00-4.62 whereas that of Gahnite is 4.00-4.62.
