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

Sulfur and Verdelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sulfur and Verdelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sulfur and Verdelite Optical Properties during the identification of gemstone. Specific gravity of Sulfur is 2.90-3.40 whereas that of Verdelite is 2.90-3.40.
