While comparing Vermeil and Wernerite 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 Vermeil and Wernerite chemical formula.
Another important criteria for qualitative analysis of gemstones is Vermeil and Wernerite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Vermeil and Wernerite Optical Properties during the identification of gemstone. Specific gravity of Vermeil is 2.50-2.80 whereas that of Wernerite is 2.50-2.80.
