While comparing Thomsonite and Amblygonite 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 Thomsonite and Amblygonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Thomsonite and Amblygonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thomsonite and Amblygonite Optical Properties during the identification of gemstone. Specific gravity of Thomsonite is 2.98-3.10 whereas that of Amblygonite is 2.98-3.10.
