While comparing Villiaumite and Turquoise 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 Turquoise chemical formula.
Another important criteria for qualitative analysis of gemstones is Villiaumite and Turquoise Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Villiaumite and Turquoise Optical Properties during the identification of gemstone. Specific gravity of Villiaumite is 2.30-2.90 whereas that of Turquoise is 2.30-2.90.
