The Iron Ring is a ring worn by many Canadian-trained engineers, as a symbol and reminder of the obligations and ethics associated with their profession. The ring is presented to engineering graduates in a private ceremony known as the Ritual of the Calling of an Engineer. The concept of the ritual and the rings originated from H. E. T. Haultain in 1922, with assistance from Rudyard Kipling, who crafted the ritual at Haultain's request.
The Iron Ring is designed with facets on the ring's outer surface.

A pinky ring is any ring worn on the pinky, or little finger, of either hand. A pinky ring may have special significance conferred by the wearer's office or professional association, but may also may be worn purely for fashion. Signet rings, which hold their own meaning, are often worn on the pinky.
