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

Verdelite and Morganite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Verdelite and Morganite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Verdelite and Morganite Optical Properties during the identification of gemstone. Specific gravity of Verdelite is 2.71-2.90 whereas that of Morganite is 2.71-2.90.
