While comparing Tortoiseshell and Baryte 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 Tortoiseshell and Baryte chemical formula.
Another important criteria for qualitative analysis of gemstones is Tortoiseshell and Baryte Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tortoiseshell and Baryte Optical Properties during the identification of gemstone. Specific gravity of Tortoiseshell is 4.3-5 whereas that of Baryte is 4.3-5.
