Chemists' Ring

Chemists' Ring

The Chemists' Ring is a ring worn by a chemist who has earned the designation of "Professional Chemist" through the Association of the Chemical Profession of Alberta (ACPA).[1] The Ring is seen by Professional Chemists as a symbol that the wearer meets the trust and ethical requirements of the ACPA. Wearing it is also a tangible way for the public and other professionals to recognize a Professional Chemist.

Chemist's Ring

About

The Chemist's Ring is normally worn on the last finger of the dominant (working) hand. The shape of the ring - a hexagon with a circle in the middle - is instantly identifiable to any person with a good knowledge of chemistry as it represents a classic organic chemical: benzene, which when in its pure form is commonly referred to as the benzene ring.[2]

History

The Chemist's Ring was originally designed by David Gibson, who as a young chemist designed the ring's mold while working in his family's jewelry business. When other Professional Chemists asked Mr. Gibson about his ring, some discussion followed and with Mr. Gibson's permission, the ACPA adopted the Ring's design. They also allow other professional chemical societies to adopt the Ring's design.

The Engineer's Ring is similar in concept to the Chemist's Ring.
