While comparing Villiaumite and Aqua Aura 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 Villiaumite and Aqua Aura chemical formula.
Another important criteria for qualitative analysis of gemstones is Villiaumite and Aqua Aura Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Villiaumite and Aqua Aura Optical Properties during the identification of gemstone. Specific gravity of Villiaumite is Not Available whereas that of Aqua Aura is Not Available.
