While comparing Barite and Annabergite 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 Barite and Annabergite chemical formula.
Another important criteria for qualitative analysis of gemstones is Barite and Annabergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Barite and Annabergite Optical Properties during the identification of gemstone. Specific gravity of Barite is 3.07 whereas that of Annabergite is 3.07.
