While comparing Tugtupite and Ametrine 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 Tugtupite and Ametrine chemical formula.
Another important criteria for qualitative analysis of gemstones is Tugtupite and Ametrine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tugtupite and Ametrine Optical Properties during the identification of gemstone. Specific gravity of Tugtupite is 2.65 whereas that of Ametrine is 2.65.
