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

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