While comparing Johachidolite and Selenite 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 Johachidolite and Selenite chemical formula.
Another important criteria for qualitative analysis of gemstones is Johachidolite and Selenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Johachidolite and Selenite Optical Properties during the identification of gemstone. Specific gravity of Johachidolite is Not Available whereas that of Selenite is Not Available.
