Smithsonite and Pleonaste Chemical Formula
While comparing Smithsonite and Pleonaste 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 Smithsonite and Pleonaste chemical formula.

Smithsonite and Pleonaste Specific Gravity
Another important criteria for qualitative analysis of gemstones is Smithsonite and Pleonaste Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Smithsonite and Pleonaste Optical Properties during the identification of gemstone. Specific gravity of Smithsonite is 3.80 whereas that of Pleonaste is 3.80.
