While comparing Abalone and Galena 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 Abalone and Galena chemical formula.
Another important criteria for qualitative analysis of gemstones is Abalone and Galena Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Abalone and Galena Optical Properties during the identification of gemstone. Specific gravity of Abalone is 6.23 whereas that of Galena is 6.23.
