Willemite and Pleonast Chemical Formula
While comparing Willemite and Pleonast 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 Willemite and Pleonast chemical formula.

Willemite and Pleonast Specific Gravity
Another important criteria for qualitative analysis of gemstones is Willemite and Pleonast Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Willemite and Pleonast Optical Properties during the identification of gemstone. Specific gravity of Willemite is Not Available whereas that of Pleonast is Not Available.
