While comparing Halite and Richterite 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 Halite and Richterite chemical formula.
Another important criteria for qualitative analysis of gemstones is Halite and Richterite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Halite and Richterite Optical Properties during the identification of gemstone. Specific gravity of Halite is 3.0-3.5 whereas that of Richterite is 3.0-3.5.
