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

Kyanite and Phosgenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Kyanite and Phosgenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kyanite and Phosgenite Optical Properties during the identification of gemstone. Specific gravity of Kyanite is 6.13 whereas that of Phosgenite is 6.13.
