While comparing Tinzenite and Serendibite 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 Tinzenite and Serendibite chemical formula.
Another important criteria for qualitative analysis of gemstones is Tinzenite and Serendibite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tinzenite and Serendibite Optical Properties during the identification of gemstone. Specific gravity of Tinzenite is 3.43-3.44 whereas that of Serendibite is 3.43-3.44.
