While comparing Pargasite and Tinzenite 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 Pargasite and Tinzenite chemical formula.
Another important criteria for qualitative analysis of gemstones is Pargasite and Tinzenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pargasite and Tinzenite Optical Properties during the identification of gemstone. Specific gravity of Pargasite is 3.355-3.433 whereas that of Tinzenite is 3.355-3.433.
