Diamonds which are nearly round due to the stepping tendency of octahedrons are commonly coated in a gum-like skin ("nyf "); the combination of stepped faces, growth defects, and nyf produces a"scaly" or corrugated appearance.
The combination of stepped faces, growth defects, and nyf produces a"scaly" or corrugated appearance. Diamonds which are nearly round, due to the formation of multiple steps on octahedral faces, are commonly coated in a gum-like skin ("nyf ").
