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

Verdelite and Seraphinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Verdelite and Seraphinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Verdelite and Seraphinite Optical Properties during the identification of gemstone. Specific gravity of Verdelite is 2.60-3.02 whereas that of Seraphinite is 2.60-3.02.
