While comparing Thulite and Papagoite 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 Thulite and Papagoite chemical formula.
Another important criteria for qualitative analysis of gemstones is Thulite and Papagoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thulite and Papagoite Optical Properties during the identification of gemstone. Specific gravity of Thulite is 3.25 whereas that of Papagoite is 3.25.
