While comparing Barite and Thulite 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 Thulite chemical formula.
Another important criteria for qualitative analysis of gemstones is Barite and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Barite and Thulite Optical Properties during the identification of gemstone. Specific gravity of Barite is 3.1 whereas that of Thulite is 3.1.
