While comparing Chrysoprase and Pollucite 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 Chrysoprase and Pollucite chemical formula.
Another important criteria for qualitative analysis of gemstones is Chrysoprase and Pollucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Pollucite Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 2.86-2.94 whereas that of Pollucite is 2.86-2.94.
