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

Phosgenite and Achroite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Phosgenite and Achroite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosgenite and Achroite Optical Properties during the identification of gemstone. Specific gravity of Phosgenite is 2.90-3.40 whereas that of Achroite is 2.90-3.40.
