While comparing Paraiba and Anyolite 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 Paraiba and Anyolite chemical formula.
Another important criteria for qualitative analysis of gemstones is Paraiba and Anyolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Paraiba and Anyolite Optical Properties during the identification of gemstone. Specific gravity of Paraiba is 3.20-3.50 whereas that of Anyolite is 3.20-3.50.
