While comparing Baryte and Alabaster 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 Baryte and Alabaster chemical formula.
Another important criteria for qualitative analysis of gemstones is Baryte and Alabaster Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Baryte and Alabaster Optical Properties during the identification of gemstone. Specific gravity of Baryte is 2.30 whereas that of Alabaster is 2.30.
