While comparing Bertrandite and Chrysoprase 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 Bertrandite and Chrysoprase chemical formula.
Another important criteria for qualitative analysis of gemstones is Bertrandite and Chrysoprase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bertrandite and Chrysoprase Optical Properties during the identification of gemstone. Specific gravity of Bertrandite is 2.58-2.64 whereas that of Chrysoprase is 2.58-2.64.
