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

Sulfur and Emerald Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sulfur and Emerald Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sulfur and Emerald Optical Properties during the identification of gemstone. Specific gravity of Sulfur is 2.67-2.78 whereas that of Emerald is 2.67-2.78.
