While comparing Hambergite and Kainite 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 Hambergite and Kainite chemical formula.
Another important criteria for qualitative analysis of gemstones is Hambergite and Kainite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hambergite and Kainite Optical Properties during the identification of gemstone. Specific gravity of Hambergite is 2.15 whereas that of Kainite is 2.15.
