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