While comparing Jasper and Fire Agate 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 Jasper and Fire Agate chemical formula.
Another important criteria for qualitative analysis of gemstones is Jasper and Fire Agate Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jasper and Fire Agate Optical Properties during the identification of gemstone. Specific gravity of Jasper is 2.60-2.64 whereas that of Fire Agate is 2.60-2.64.
