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

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