While comparing Eosphorite and Thomsonite 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 Eosphorite and Thomsonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Eosphorite and Thomsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Eosphorite and Thomsonite Optical Properties during the identification of gemstone. Specific gravity of Eosphorite is 2.25-2.40 whereas that of Thomsonite is 2.25-2.40.
