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

Verdelite and Agate Specific Gravity
Another important criteria for qualitative analysis of gemstones is Verdelite and Agate Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Verdelite and Agate Optical Properties during the identification of gemstone. Specific gravity of Verdelite is 2.60-2.64 whereas that of Agate is 2.60-2.64.
