Pollucite and Prasiolite Chemical Formula
While comparing Pollucite and Prasiolite 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 Pollucite and Prasiolite chemical formula.

Pollucite and Prasiolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pollucite and Prasiolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pollucite and Prasiolite Optical Properties during the identification of gemstone. Specific gravity of Pollucite is 2.65 whereas that of Prasiolite is 2.65.
