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