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