Phosgenite and Marialite Chemical Formula
While comparing Phosgenite and Marialite 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 Marialite chemical formula.

Phosgenite and Marialite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Phosgenite and Marialite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosgenite and Marialite Optical Properties during the identification of gemstone. Specific gravity of Phosgenite is 2.50 whereas that of Marialite is 2.50.
