While comparing Ammolite and Moldavite 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 Ammolite and Moldavite chemical formula.
Another important criteria for qualitative analysis of gemstones is Ammolite and Moldavite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ammolite and Moldavite Optical Properties during the identification of gemstone. Specific gravity of Ammolite is 2.32-2.38 whereas that of Moldavite is 2.32-2.38.
