While comparing Barite and Spessartine 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 Spessartine chemical formula.
Another important criteria for qualitative analysis of gemstones is Barite and Spessartine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Barite and Spessartine Optical Properties during the identification of gemstone. Specific gravity of Barite is 4.12-4.18 whereas that of Spessartine is 4.12-4.18.
