While comparing Phosgenite and Jeremejevite 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 Phosgenite and Jeremejevite chemical formula.
Another important criteria for qualitative analysis of gemstones is Phosgenite and Jeremejevite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosgenite and Jeremejevite Optical Properties during the identification of gemstone. Specific gravity of Phosgenite is 3.28-3.31 whereas that of Jeremejevite is 3.28-3.31.
