While comparing Vermeil and Fluorite 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 Fluorite chemical formula.
Another important criteria for qualitative analysis of gemstones is Vermeil and Fluorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Vermeil and Fluorite Optical Properties during the identification of gemstone. Specific gravity of Vermeil is 3.00-3.25 whereas that of Fluorite is 3.00-3.25.
