While comparing Langbeinite and Wavellite 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 Langbeinite and Wavellite chemical formula.
Another important criteria for qualitative analysis of gemstones is Langbeinite and Wavellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Langbeinite and Wavellite Optical Properties during the identification of gemstone. Specific gravity of Langbeinite is 2.36 whereas that of Wavellite is 2.36.
