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

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